MPC9449集成電路（IC）的時鐘緩沖器驅動器規(guī)格書PDF中文資料

The MPC9449 is a 3.3 V or 2.5 V compatible, 1:15 clock fanout buffer targeted

for high performance clock tree applications. With output frequencies up to

200 MHz and output skews less than 200 ps the device meets the needs of the

most demanding clock applications.
