Functional Description

The CY29942 is a low voltage clock distribution buffer with an LVCMOS or LVTTL compatible clock input. The output enable control input is LVCMOS/LVTTL compatible. The eighteen outputs are 2.5 V or 3.3 V LVCMOS or LVTTL compatible, operate up to 200 MHz, 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.
