SY897132L
1.5Gbps Link Replicator for Fibre Channel, Gigabit Ethernet, HDTV and SATA
General Description
The SY897132L is a Link Replicator which provides both serial loop replication as well as serial loopback control functions. It is high performance and works up to 1.5Gbps on 3.3V power supplies. The SY897132L is ideal for Fibre Channel, Gigabit Ethernet, HDTV and SATA applications. Other applications include internal/external connection routing in Host Bus Adaptors as well as hot-pluggable links between switch cards. The IN input is sent to both OUT0 and OUT1, which are enabled when OE0 and OE1 are HIGH and disabled when they are LOW. When the outputs are disabled, both differential outputs go HIGH and the buffers are turned off to save power. MUX0 controls whether IN or IN1 is sent to OUT0. Similarly, MUX1 controls whether IN or IN0 is sent to OUT1. MUX selects whether IN0 or IN1 is sent to OUT. The SY897132L operates on 3.3V 5% power supplies and is guaranteed over the full industrial temperature range (-40C to +85C). The SY897132L is part of Micrel's high-speed, Precision Edge(R) product line. Datasheets and support documentation can be found on Micrel's web site at: www.micrel.com.

Notes: 1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability. 2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings. 3. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the device's most negative potential on the PCB. JB and JA values are determined for a four-layer board in still-air number, unless otherwise stated. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established. 4. JEDEC standard multilayer board -2S2P (2 signal, 2 power) 5.

Notes: 6. Output-to-Output skew is the difference in time between both outputs, receiving data from the same input, for the same temperature, voltage and transition. 7. Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and no skew at the edges at the respective inputs. 8. Deterministic jitter is measured at 1.5Gbps with both K28.5 and 2 -1 PRBS pattern.

Detailed Description
Input Functionality The inputs are typically AC-coupled and are terminated internally to 1.2V. SY897132L can accept AC-coupled and DC-coupled LVPECL, CML. Outputs Termination The SY897132L are capable of driving differential transmission lines with either 50 or 75 impedance. The outputs are designed to operate with or without external termination resistors. However, differential transmission lines should be terminated at the destination to avoid reflections and noise. See Figure 3 for more details. OEx Output Enable The Output Enable (OEx) pins on the SY897132L provide an option to turn on/off OUT0 and/or OUT1. If OEx is LOW, the entire output buffer is turned off and both differential outputs float HIGH. This would reduce overall ICC by approximately 26mA for each disabled output pair. Power Supply Bypass The SY897132L uses separate 3.3V power supplies for its core circuitry and output buffers. By separating the power supplies, SY897132L minimizes the impact of noise coupled onto the power supply by the various switching outputs. Placing a 0.1F bypass capacitor on the VCC pins will provide additional noise isolation.
