CY29942

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

Features

Description

• 200-MHz clock support

• 2.5V or 3.3V operation

The CY29942 is a low-voltage 200-MHz clock distribution buff-

er with an LVCMOS or LVTTL 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 50 Ω series or parallel terminated transmission lines.

For series terminated transmission lines, each output can

drive one or two traces giving the devices an effective fanout

of 1:36. Low output-to-output skews make the CY29942 an

ideal clock distribution buffer for nested clock trees in the most

demanding of synchronous systems.

• LVCMOS/LVTTL clock input

• 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 MPC942C

• Available in Industrial and Commercial

• 32-pin LQFP package
