rev. 1.0 7/06 copyright ? 2006 by silicon laboratories si530/531 si530/531 c rystal o scillator (xo) (10 mh z to 1.4 gh z ) features applications description the si530/531 xo utilizes silicon laboratories? advanced dspll ? circuitry to provide a low jitter clock at high frequencies. the si530/531 is available with any-rate output frequency from 10 to 945 mhz and select frequencies to 1400 mhz. unlike a traditional xo, where a different crystal is required for each output frequency, the si530/531 uses one fixed crystal to provide a wide range of output frequencies. this ic based approach allows the crystal resonator to provide exceptional frequency stability and reliability. in addition, dspll clock synthesis provides superior supply noise rejection, simplifying the task of generating low jitter clocks in noisy environments typically found in communication systems. the si530/531 ic based xo is factory configurable for a wide variety of user specifications including frequency, supply voltage, output format, and temperature stability. specific configurations are factory programmed at time of shipment, thereby eliminating long lead times associated with custom oscillators. functional block diagram available with any-rate output frequencies from 10 mhz to 945 mhz and select frequencies to 1.4 ghz 3rd generation dspll ? with superior jitter performance 3x better frequency stability than saw-based oscillators internal fixed crystal frequency ensures high reliability and low aging available cmos, lvpecl, lvds, and cml outputs 3.3, 2.5, and 1.8 v supply options industry-standard 5 x 7 mm package and pinout pb-free/rohs-compliant sonet/sdh networking sd/hd video test and measurement clock and data recovery fpga/asic clock generation fixed frequency xo any-rate 10?1400 mhz dspll ? clock synthesis v dd clk+ clk? oe gnd ordering information: see page 7. pin assignments: see page 6.
