CDCLVP1102

SCAS884D – AUGUST 2009 – REVISED DECEMBER 2015

CDCLVP1102 Two-LVPECL Output,

High-Performance Clock Buffer

1 Features

3 Description

The CDCLVP1102 is a highly versatile, low additive

1:2 Differential Buffer

jitter buffer that can generate two copies of LVPECL

Single Clock Input

clock outputs from one LVPECL, LVDS, or LVCMOS

•

Universal Inputs Can Accept LVPECL, LVDS,

input for a variety of communication applications. It

LVCMOS/LVTTL

has a maximum clock frequency up to 2 GHz. The

overall additive jitter performance is less than 0.1 ps,

choice for use in demanding applications.

•

Very Low Additive Jitter: <100 fs, RMS in 10-kHz

The CDCLVP1102 clock buffer distributes a single
