1:18 Clock Distribution Buffer

42 CY29942 2.5V or 3.3V, 200-MHz, 1:18 Clock Distribution Buffer Features • • • • • • • • • • 200-MHz clock support 2.5V or 3.3V operation 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 Description The CY29942 is a low-voltage 200-MHz clock distribution buffer 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.
