MPC940L集成電路（IC）的應用特定時鐘/定時規(guī)格書PDF中文資料

The MPC940L is a 1:18 low voltage clock distribution chip with 2.5 V or 3.3 V LVCMOS

output capabilities. The device features the capability to select either a differential

LVPECL or an LVCMOS compatible input. The 18 outputs are 2.5 V or 3.3 V LVCMOS

compatible and feature the drive strength to drive 50 ? series or parallel terminated

transmission lines. With output-to-output skews of 150 ps, the MPC940L 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 high performance microprocessor

based design. For a similar device at a lower price/performance point, the reader is

referred to the MPC9109.
