Clock Generator for PowerQUICC and PowerPC Microprocessors

The MPC9855 is a PLL based clock generator specifically designed for Freescale Microprocessor and Microcontroller applications including the PowerPC and PowerQUICC. This device generates a microprocessor input clock. The microprocessor clock is selectable in output frequency to any of the commonly used microprocessor input and bus frequencies. The device offers eight low skew clock outputs in two banks, each configurable to support different clock frequencies. The extended temperature range of the MPC9855 supports telecommunication and networking requirements.
