MPC93H51集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

The MPC93H51 is a 3.3 V compatible, PLL based clock generator targeted for

high performance clock distribution systems. With output frequencies of up to

240 MHz and a maxi mum output skew of 150 ps the MPC93H51 is an ideal

solution for the most demanding clock tree designs. The device offers 9 low skew

clock outputs. Each is configurable to support the clocking needs of the various

high-performance microprocessors including the PowerQuicc II integrated

communication microprocessor. The devices employs a fully differential PLL

design to minimize cycle-to-cycle and long-term jitter.
