Description
The ICS548-05 is a low-cost, low-jitter,
high-performace clock synthesizer designed to
produce x16 and x24 clocks from T1 and E1
frequencies. Using IDT’s patented analog/digital
Phase- Locked Loop (PLL) techniques, the device uses
a crystal or clock input to synthesize popular
communications frequencies. Power down modes allow
the chip to turn off completely, or the PLL and clock
output to be turned off separately.
IDT manuafactures the largest variety of
communications clock synthesizers for all applications.
Consult IDT to eliminate VCXO’s, crystals, and
oscillators from your board.
