Low Voltage PLL Clock Driver

The MPC9350 is a 2.5V and 3.3V compatible, PLL based clock generator targeted for high performance clock distribution systems. With output frequencies of up to 200 MHz and maximum output skews of 150 ps the MPC9350 is ideal 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 extended temperature range of the MPC9350 supports telecommunication and networking requirements. The devices employs a fully differential PLL design to minimize cycle-to-cycle and long-term jitter.
