PCK942C Low Voltage 1 : 18 Clock Distribution Chip

The PCK942C is a 1 : 18 low voltage Clock Distribution chip with 2.5 V or 3.3 V LVCMOS output capabilities. The device is offered in two versions: the PCK942C has an LVCMOS input Clock while the PCK942P has an LVPECL input Clock The 18 outputs are 2.5 V or 3.3 V LVCMOS compatible and feature the drive strength to drive 50 Ohm series or parallel terminated transmission lines. With output-to-output skews of 200 ps, the PCK942C is ideal as a Clock Distribution chip for the most demanding of synchronous systems. The 2.5 V outputs also make the device ideal for supplying Clocks for a higher performance Pentium II Microprocessor based design. With a low output impedance of approximately 12 Ohm, in both the HIGH and LOW Logic states, the output Buffers of the PCK942C are ideal for driving series terminated transmission lines. With an output impedance of 12 Ohm the PCK942C CAN drive two series terminated transmission lines from each output. This capability gives the PCK942C an effective fan-out of 1 : 36. The PCK942C provides enough copies of low skew Clocks for most high performance synchronous systems. The LVCMOS/LVTTL input of the PCK942C provides a more standard LVCMOS Interface The OE pin will place the outputs into a high-impedance state. The OE pin has an internal pull-up resistor. The PCK942C is a single supply device. The VCC power pins require either 2.5 V or 3.3 V. The 32-lead LQFP package was chosen to optimize performance, board space, and cost of the device. The 32-lead LQFP package has a 7 mm x 7 mm body size with a conservative 0.8 mm pin spacing.
