Silicon Labs has leveraged its proven DSPLL® technology
to create user-programmable XOs and VCXOs that provide any-rate frequency synthesis. The Si570 any-rate programmable XO and the Si571 any-rate programmable VCXO generate any frequency from 10 MHz to 1.4 GHz and target low jitter applications requiring reconfigurable clock sources. The Si57x replaces multiple discrete fixed-frequency oscillators with a single device, minimizing system costs and simplifying design reuse while improving system reliability.
Targeting high-performance timing applications, the Si57x provide outstanding frequency flexibility and jitter performance. For relaxed jitter and lower frequency applications, the Si598/599 and Si514 offer lower cost alternatives.
