Skyworks 570AAA000122DG

晶体XO（标准）1 GHz启用/禁用（可编程）LVPECL3.3V±50ppm

Overview

The Si570 XO utilizes Silicon Laboratories’ advanced DSPLL® circuitry to provide a low-jitter clock at any frequency. The Si570 are user-programmable to any output frequency from 10 to 945 MHz and select frequencies to 1400 MHz with <1 ppb resolution. The device is programmed via an I²C serial interface. Unlike traditional XOs where a different crystal is required for each output frequency, the Si57x uses one fixed-frequency crystal and a DSPLL clock synthesis IC to provide any-frequency operation. 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.Applications:• SONET/SDH• xDSL• 10 GbE LAN/WAN• ATE • High performance instrumentation• Low-jitter clock generation• Optical modules• Clock and data recovery
