841664I中文资料FemtoClock® Crystal-to-HCSL Clock Generator数据手册Renesas规格书

描述 Description

The 841664I is an optimized sRIO clock generator and a member of the family of high-performance clock solutions from IDT. The device uses a 25MHz parallel crystal to generate 125MHz and 156.25MHz clock signals, replacing solution requiring multiple oscillator and fanout buffer solutions. The device has excellent phase jitter (
