Silicon Laboratories Inc. announces its Si570/1 family of user-programmable crystal oscillators (XO) and voltage-controlled crystal oscillators (VCXO) that supporting any-rate frequency synthesis. Using proprietary DSPLL technology and an industry-standard I2C interface, a single device can generate any output frequency from 10 MHz to 1.4 GHz at jitter levels of 0.3 picoseconds rms. The Si570 Any-Rate XO and Si571 Any-Rate VCXO are suitable for high-performance applications requiring frequency flexible clock sources, including next-generation networking equipment, wireless base stations, test and measurement equipment, HDTV video infrastructure and high-speed data acquisition equipment. The XO and VCXO address the need for low jitter, frequency-flexible clock sources, enabling hardware designers to decrease the number of oscillators in their designs.
