| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Product Preview Low Voltage CMOS 1:18 Clock Distribution Chip The MPC909 is a 1:18 low voltage clock distribution chip. The 18 outputs are LVCMOS or LVTTL compatible and feature the drive strength to drive 50 series or parallel terminated transmission lines. With output-to-output skews of 250ps, the MPC909 is ideal as a clock distribution chip for the cost sensitive, high performance designs. With low cost as one of the critical parameters, technology, design and test choices were made which adversely affect part-to-part skew performance. For very high performance applications, where part-to-part skew is critical, please refer to the MPC940 datasheet. MPC909 LOW VOLTAGE CMOS 1:18 CLOCK DISTRIBUTION CHIP * * * * * * * LVCMOS/LVTTL Clock Inputs and Outputs 250ps Maximum Targeted Output-to-Output Skew Drives Up to 36 Independent Clock Lines Maximum Output Frequency of 100MHz High Impedance Output Enable 32-Lead TQFP Packaging 3.3V VCC Supply Voltage FA SUFFIX 32-LEAD TQFP PACKAGE CASE 873A-02 With a low output impedance, in both the HIGH and LOW logic states, the output buffers of the MPC909 are ideal for driving series terminated transmission lines. More specifically, each of the 18 MPC909 outputs can drive two series terminated 50 transmission lines. With this capability, the MPC909 has an effective fanout of 1:36 in applications where each line drives a single load. With this level of fanout, the MPC909 provides enough copies of low skew clocks for many high performance synchronous systems. The MPC909 is fully 3.3V compatible. The 32-lead TQFP package was chosen to optimize performance, board space and cost of the device. The 32-lead TQFP has a 7x7mm body size with a conservative 0.8mm pin spacing.
