Low Jitter PLLs Switches/routers xDSL FPGA/ASIC clock generation 1 V 6 Vc DD Description 2 5 FS NC The Si516 dual frequency VCXO utilizes Skyworks Solutions advanced PLL technology to provide any frequency from 100 kHz to 250 MHz. Unlike a 3 4 CLK GND traditional VCXO where a different crystal is required for each output frequency, the Si516 uses one fixed crystal and Skyworks Solutions CMOS Dual VCXO proprietary synthesizer to generate any frequency across this range. This IC- based approach allows the crystal resonator to provide enhanced reliability, improved mechanical robustness, and excellent stability. In addition, this 1 V 6 Vc DD solution provides superior control voltage linearity and supply noise rejection, improving PLL stability and simplifying low jitter PLL design in 2 5 CLK FS noisy environments. The Si516 is factory-configurable for a wide variety of user specifications, including frequency, supply voltage, output format, 3 4 CLK+ GND tuning slope and stability. Specific configurations are factory-programmed at LVPECL/LVDS/HCSL/Dual CMOS time of shipment, eliminating long lead times and non-recurring engineering Dual VCXO charges associated with custom frequency oscillators.
