Clock Generator for PowerQUICC III
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.

Functional Description
The MPC9855 uses either a 25 or 33 MHz reference frequency to generate 8 LVCMOS output clocks, of which, the frequency
is selectable from 16 MHz to 200 MHz. The reference is applied to the input of a PLL and multiplied to 2 GHz. Output dividers,
divide this frequency by 10, 12, 15, 16, 18, 20, 24, 30, 40, 60, or 120 to produce output frequencies of 200, 166, 133, 125, 111,
100, 83, 66, 50, 33, or 16 MHz. The single-ended LVCMOS outputs provide 8 low skew outputs for use in driving a microprocessor
or microcontroller clock input as well as other system components. The input reference, either crystal or external input is also
buffered to a separate dual outputs that my be used as the clock source for a Ethernet PHY if desired.
The reference clock may be provided by either an external clock input of 25 or 33 MHz. An internal oscillator requiring a
25 MHz crystal for frequency control may also be used. The external clock source my be applied to either of two clock inputs and
selected via the CLK_SEL control input. Both single ended LVCMOS and differential LVPECL inputs are available. The crystal
oscillator or external clock input is selected via the input pin of XTAL_SEL. Other than the crystal, no external components are
required for crystal oscillator operation. The REF_33 MHz configuration pin is used to select between a 33 and 25 MHz input
frequency.
The MPC9855 is packaged in a 100 lead MAPBGA package to optimize both performance and board density.
