Input from fundamental crystal oscillator or external source
Internal PLL feedback (loading feedback output relative to
other outputs, adjusts propagation delay between REF inputs
and outputs)
Select inputs (S

The IDT5V927 is a low-cost, low skew, low jitter, and high-performance
clock synthesizer. It has been specially designed to interface with Gigabit
Ethernet (125MHz), Fibre Channel (106.25MHz), and OC-3 (155.52MHz)
applications. It can be programmed to provide output frequencies ranging
from 50MHz to 160MHz, with input frequencies ranging from 6.25MHz to
80MHz.
The IDT5V927 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?
