PCS2I9942P  
Low Voltage 1:18 Clock Distribution Chip  
Features  
With low output impedance (12), in both the HIGH and  
LOW logic states, the output buffers of the PCS2I9942P  
are ideal for driving series terminated transmission lines.  
With an output impedance of 12, the PCS2I9942P can  
drive two series terminated transmission lines from each  
output. This capability gives the PCS2I9942P an effective  
fanout of 1:36. The PCS2I9942P provides enough copies  
of low skew clocks for most high performance synchronous  
systems.

Functional Description  
The differential LVPECL inputs of the PCS2I9942P allow  
the device to interface directly with a LVPECL fanout buffer  
to build very wide clock fanout trees or to couple to a high  
frequency clock source. The OE pins will place the outputs  
into a high impedance state. The OE pin has an internal  
pullup resistor.  
The PCS2I9942P is a 1:18 low voltage clock distribution  
chip with 2.5V or 3.3V LVCMOS output capabilities. The  
device is offered in two versions; the PCS2I9942C has an  
LVCMOS input clock while the PCS2I9942P has a LVPECL  
input clock. The 18 outputs are 2.5V or 3.3V LVCMOS  
compatible and feature the drive strength to drive 50Ω  
series or parallel terminated transmission lines. With  
output-to-output skews of 200pS, the PCS2I9942P is ideal  
as a clock distribution chip for the most demanding of  
synchronous systems. The 2.5V outputs also make the  
device ideal for supplying clocks for a high performance  
Pentium IITM microprocessor based design.  
The PCS2I9942P is a single supply device. The VCC power  
pins require either 2.5V or 3.3V. The 32 lead LQFP and  
TQFP package is chosen to optimize performance, board  
space and cost of the device. The 32–lead LQFP and  
TQFP have a 7x7mm2 body size with conservative 0.8mm  
pin spacing.
