The IDT5V926 is a low-cost, low skew, low jitter, and high-performance
clock synthesizer with a reference clock from lower frequency crystal or clock
input. It has been specially designed to interface with Gigabit Ethernet and
Fast Ethernet applications by providing a 125MHz clock from 25MHz input.
It can be programmed to provide output frequencies ranging from 48MHz
to 160MHz, with input frequencies ranging from 6MHz to 80MHz.
The IDT5V926 includes an internal RC filter that provides excellent jitter
characteristics and eliminates the need for external components. When
using the optional crystal input, the chip accepts a 10 - 40MHz fundamental
mode crystal with a maximum equivalent series resistance of 50鈩?
