描述 Description

The 5V49EE902-255 is s a programmable clock generator

intended for high performance data-communications,

telecommunications, consumer, and networking applications.

There are four internal PLLs, each individually programmable,

allowing for four unique non-integer-related frequencies. The

frequencies are generated from a single reference clock.

The IDT5V49EE902 datasheet contains detailed information on

how to configure this device.
