Description:: IC CLK BUFFER 1:18 200MHZ 32TQFP

ECAD Model:

Datasheet:: CY29942AXIT

Overview

Description
The CY29942 is a lowvoltage clock distribution buffer with an LVCMOS or LVTTLcompatible clock input and output enable control input. It features 18 LVCMOS or LVTTLcompatible outputs that can operate up to 200 MHz and drive up to 36 clock lines. The low outputtooutput skew makes it suitable for nested clock trees in demanding synchronous systems.

Features
Operational range: Up to 200 MHz
LVCMOS/LVTTL clock input

Outputtooutput Skew: 110 ps (typical)
Output enable control
Supply voltage: 2.5 V or 3.3 V
Temperature range: Commercial and Industrial
32pin TQFP package
Pin compatible with MPC942C

Applications
Clock distribution in highspeed synchronous systems
Nested clock trees
Driving multiple clock lines
Fanout buffer for clock signals
