IDT 843N571I
The 843N571I is a PLL based clock synthesizer for use in Ethernet applications. The device uses IDT’s fourth generation FemtoClock® NG technology for optimal high clock frequency and low phase noise performance, combined with a low power consumption and high power supply noise rejection. Using IDT’s latest FemtoClock NG PLL technology, the 843N571I achievesDESCRIPTION
<0.3ps RMS phase jitter performance. 843N571I can synthesize 100MHz, 125MHz, 156.25MHz and a low frequency 33.33MHz CPU clock from a single device. Six LVCMOS outputs also serve as additional buffering of the 25MHz crystal reference.FEATURES
