MPC9351 - Block Diagram
説明
The MPC9351 is a 2.5 V and 3.3 V compatible, PLL based clock generator targeted for high performance clock distribution systems. With output frequencies of up to 200 MHz and a maximum output skew of 150 ps, the MPC9351 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 extended temperature range of the MPC9351 supports telecommunication and networking requirements.The device employs a fully differential PLL design to minimize cycle-to-cycle and long-term jitter.
