MPC940L

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information Low Voltage 1:18 Clock Distribution Chip The MPC940L is a 1:18 low voltage clock distribution chip with 2.5V LVCMOS output capabilities. The device features the capability to select either a differential LVPECL or an LVTTL/ LVCMOS compatible input. The 18 outputs are 2.5V LVCMOS compatible and feature the drive strength to drive 50Ω series or parallel terminated transmission lines. With output–to–output skews of 150ps, the MPC940L is ideal as a clock www.DataSheet4U.com 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 II™ microprocessor based design. MPC940L LOW VOLTAGE 1:18 CLOCK DISTRIBUTION CHIP LVPECL or LVCMOS/LVTTL Clock Input 2.5V LVCMOS Outputs for Pentium II Microprocessor Support 150ps Maximum Targeted Output–to–Output Skew Maximum Output Frequency of 250MHz 32–Lead TQFP Packaging Dual VCC Supply Voltage, 3.3V Core and 2.5V Output FA SUFFIX 32–LEAD TQFP PACKAGE CASE 873A–02 With a low output impedance (≈30Ω), in both the HIGH and LOW logic states, the output buffers of the MPC940L are ideal for driving series terminated transmission lines. With this drive capability, the MPC940L provides enough copies of low skew clocks for most high performance synchronous systems. The differential LVPECL inputs of the MPC940L allow the device to interface directly with a LVPECL fanout buffer lik...
