CY29943

2.5V or 3.3V 200-MHz 1:18 Clock Distribution Buffer

Features

Description

• 200-MHz clock support

• 2.5V or 3.3V operation

• LVPECL clock input

The CY29943 is a low-voltage 200-MHz clock distribution

buffer with an LVPECL-compatible input clock. All other control

inputs are LVCMOS-/LVTTL-compatible. The eighteen outputs

are 2.5V or 3.3V LVCMOS- or LVTTL-compatible and can

drive 50Ω series or parallel terminated transmission lines. For

series terminated transmission line, each output can drive one

or two traces giving the device an effective fanout of 1:36. Low

output-to-output skews make the CY29943 an ideal clock

distribution buffer for nested clock trees in the most

demanding of synchronous systems.

• LVCMOS-/LVTTL-compatible inputs

• 18 clock outputs: drive up to 36 clock lines

• 200 ps max. output-to-output skew

• Output Enable control

• Pin compatible with MPC942P

• Available in Industrial and Commercial

• 32-pin LQFP package
