5 S2102 dual fibre channel device october 6, 2000 / revision c figure 5. din data clocking with tbc transmitter description the transmitter section of the S2102 contains a single pll which is used to generate the serial rate transmit clock for all transmitters. two channels are provided with a variety of options regarding input clocking and loopback. the transmitters operate at 1.062 ghz, 10 or 20 times the reference clock frequency. data input the S2102 has been designed to simplify the parallel interface data transfer and provides the utmost in flex- ibility regarding clocking of parallel data. the S2102 incorporates a unique fifo structure on both the par- allel inputs and the parallel outputs which enables the user to provide a clean reference source for the pll and to accept a separate external clock which is used exclusively to reliably clock data into the device. data can also be clocked in using the refclk. data is input to each channel of the S2102 nominally as a 10 bit wide word. an input fifo and a clock input, tbcx, are provided for each channel of the S2102. the device can operate in two different modes. the S2102 can be configured to use either the tclkx (tclk mode) input or the refclk input (refclk mode). in tclk or refclk mode, 10 bits of data are clocked into its fifo with the tbcx provided with each 10 bits. table 1 provides a sum- mary of the input modes of the S2102. operation in the tbc mode makes it easier for us- ers to meet the relatively narrow setup and hold time window required by the 106.25 mbps 10-bit inter- face. the tbc signal is used to clock the data into an internal holding register and the S2102 synchro- nizes its internal data flow to ensure stable opera- tion. however, regardless of the clock mode, refclk is always the vco reference clock. this facilitates the provision of a clean reference clock resulting in minimum jitter on the serial output. the tbc must be frequency locked to refclk, but may have an arbitrary phase relationship. adjustment of internal timing of the S2102 is performed during re- set. once synchronized, the user must ensure that the timing of the tbc signal does not change by more than 3 ns relative to the refclk. figure 5 demonstrates the flexibility afforded by the S2102. a low jitter reference is provided directly to the S2102 at either 1/10 or 1/20 the serial data rate. this ensures minimum jitter in the synthesized clock used for serial data transmission. a system clock output at the parallel word rate, tclko, is derived from the pll and provided to the upstream circuit as a system clock. the frequency of this output is con- stant at the parallel word rate, 1/10 the serial data figure 6. fc din clocking with refclk e d o m tn o i t a r e p o 0 a t a d k c o l c o t d e s u k l c f e r . e d o m k l c f e r . s l e n n a h c l l a r o f s o f i f o t n i 1 s o f i f o t n i a t a d k c o l c o t d e s u x c b t . e d o m c b t . s l e n n a h c l l a r o f table 1. input modes refclk S2102 106.25 mhz or 53.125 mhz tbcx dinx[0:9] ref oscillator mac asic tclko pll refclk S2102 tbcx dinx[0:9] ref oscillator mac asic tclko pll 106.25 mhz note that internal synchronization of fifos is performed upon de-assertion of reset.

7 S2102 dual fibre channel device october 6, 2000 / revision c receiver description each receiver channel is designed to implement a serial backplane receiver function through the physi- cal layer. a block diagram showing the basic func- tion is provided in figure 4. whenever a signal is present, the receiver attempts to recover the serial clock from the received data stream. after acquiring bit synchronization, the S2102 searches the serial bit stream for the occur- rence of a k28.5 character on which to perform word synchronization. once synchronization on both bit and word boundaries is achieved, the receiver pro- vides the word-aligned data on its parallel outputs. data input a differential input receiver is provided for each channel of the S2102. each channel has a loopback mode in which the serial data from the transmitter replaces external serial data. the loopback function for each channel is enabled by its respective lpen input. the high speed serial inputs to the S2102 are inter- nally biased to vdd-1.3v. all that is required exter- nally are ac-coupling and line-to-line differential termination. clock recovery function clock recovery is performed on the input data stream for each channel of the S2102. the receiver pll has been optimized for the anticipated needs of serial backplane systems. a simple state machine in the clock recovery macro decides whether to acquire lock from the serial data input or from the reference clock. the decision is based upon the frequency and run length of the serial data inputs. if at any time the frequency or run length checks are violated, the state machine forces the vco to lock to the refer- ence clock. this allows the vco to maintain the cor- rect frequency in the absence of data. the lock to reference frequency criteria ensure that the S2102 will respond to variations in the serial data input frequency (compared to the reference fre- quency). the new lock state is dependent upon the current lock state, as shown in table 4. the run-length criteria ensure that the S2102 will respond appropriately and quickly to a loss of signal. the run-length checker flags a condition of consecu- tive ones or zeros across 12 parallel words. thus 119 or less consecutive ones or zeros does not cause signal loss, 129 or more causes signal loss, and 120 - 128 may or may not, depending on how the data aligns across byte boundaries. if both the off-frequency detect circuitry test and the run-length test are satisfied, the cru will attempt to lock to the incoming data. it is possible for the run length test to be satisfied due to noise on the inputs, even if no signal is present. in this case the receiver vco will maintain frequency accuracy to within 100 ppm of the target rate as determined by refclk. in any transfer of pll control from the serial data to the reference clock, the rbc1/0x outputs remain phase continuous and glitch free, assuring the integ- rity of downstream clocking. reference clock input a single reference clock, which serves both transmit- ter and receiver, must be provided from a low jitter clock source. the frequency of the received data stream (divided-by-10 or -20) must be within 200 ppm of the reference clock to ensure reliable locking of the receiver pll. k c o l t n e r r u c e t a t se t a t s e t a t s e t a t se t a t s y c n e u q e r f l l p ) k l c f e r . s v () k l c f e r . s v ( ) k l c f e r . s v ( ) k l c f e r . s v () k l c f e r . s v ( e t a t s k c o l w e n d e k c o l m p p 8 8 4 d e k c o l n u d e k c o l n u m p p 4 4 2 d e k c o l n u table 4. lock to reference frequency criteria

9 S2102 dual fibre channel device october 6, 2000 / revision c jtag testing the jtag implementation for the S2102 is compli- ant with the ieee1149.1 requirements. jtag is used to test the connectivity of the pins on the chip. the tap, (test access port), provides access to the test logic of the chip. when trst is asserted the tap is initialized. tap is a state machine that is controlled by tms. the test instruction and data are loaded through tdi on the rising edge of tck. when tms is high the test instruction is loaded into the instruction register. when tms is low the test data is loaded figure 8. S2102 diagnostic loopback operation cru csu other operating modes operating frequency rate the S2102 is designed to operate at the fibre chan- nel rate of 1.062 ghz. loopback mode when loopback mode is enabled, the serial data from the transmitter is provided to the serial input of the receiver, as shown in figure 8. this provides the ability to perform system diagnostics and off-line testing of the interface to verify the integrity of the serial channel. loopback mode is enabled indepen- dently for each channel using its respective loopback-enable input, lpen. test modes the reset pin is used to initialize the transmit fifos and must be asserted (low) prior to entering the normal operational state (see section transmit fifo initialization). note: serial output data remains active during loopback opera- tion to enable other system tests to be performed. into the data register. tdo changes on the falling edge of tck. all input pins, including clocks, that have boundary scan are observe only. they can be sampled in either normal operational or test mode. all output pins that have boundary scan, are observe and control. they can be sampled as they are driven out of the chip in normal operational mode, and they can be driven out of the chip in test mode using the extest instruction. since jtag testing operates only on digital signals there are some pins with analog signals that jtag does not cover. the jtag imple- mentation has the three required instruction, bypass, extest, and sample/preload. instruction code bypass 11 extest 00 sample/preload 01 id code 10 jtag instruction description: the bypass register contains a single shift-register stage and is used to provide a minimum-length serial path between the tdi and tdo pins of a component when no test operation of that component is re- quired. this allows more rapid movement of test data to and from other components on a board that are required to perform test operations. the extest instruction allows testing of off-chip cir- cuitry and board level interconnections. data would typically be loaded onto the latched parallel outputs of boundary-scan shift-register stages using the sample/preload instruction prior to selection of the extest instruction. the sample/preload instruction allows a snap- shot of the normal operation of the component to be taken and examined. it also allows data values to be loaded onto the latched parallel outputs of the boundary-scan shift register prior to selection of the other boundary-scan test instructions. the following table provides a list of the pins that are jtag tested. each port has a boundary scan regis- ter (bsr), unless otherwise noted. the following fea- tures are described: the jtag mode of each register (input, output2, or internal (refers to an internal pack- age pin)), the direction of the port if it has a bound- ary scan register (in or out), and the position of this register on the scan chain.
