Description (Top View) The Si534 quad frequency XO utilizes Silicon Laboratories advanced FS 1 DSPLL circuitry to provide a low jitter clock at high frequencies. The Si534 7 is available with any-rate output frequency from 10 to 945 MHz and select 1 6 V frequencies to 1400 MHz. Unlike a traditional XO where a different crystal is NC DD required for each output frequency, the Si534 uses one fixed crystal to provide a wide range of output frequencies. This IC based approach allows OE 2 5 CLK the crystal resonator to provide exceptional frequency stability and reliability. In addition, DSPLL clock synthesis provides superior supply noise rejection, GND 3 4 CLK+ simplifying the task of generating low jitter clocks in noisy environments 8 typically found in communication systems. The Si534 IC-based XO is factory configurable for a wide variety of user specifications including frequency, FS 0 supply voltage, output format, and temperature stability. Specific (LVDS/LVPECL/CML) configurations are factory programmed at time of shipment, thereby eliminating long lead times associated with custom oscillators.
