Clock Generator for
PowerQUICC III
The MPC9850 is a PLL based clock generator specifically designed for
Motorola Microprocessor And Microcontroller applications including the
PowerQUICC III. This device generates a microprocessor input clock plus
the 500 MHz Rapid I/O clock. The microprocessor clock is selectable in
output frequency to any of the commonly used microprocessor input and
bus frequencies. The Rapid I/O outputs are LVDS compatible. The device
offers eight low skew clock outputs organized into two output banks, each
configurable to support different clock frequencies. The extended
temperature range of the MPC9850 supports telecommunication and
networking requirements.

Functional Description
The MPC9850 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 are divided into two banks of 4 low skew outputs each, for use in
driving a microprocessor or microcontroller clock input as well as other system components. The 2 GHz PLL output frequency is
also divided to produce a 125, 250 or 500 MHz clock output for Rapid I/O applications such as found on the PowerQUICC III
communications processor. The input reference, either crystal or external input is also buffered to a separate output that my be
used as the clock source for a Gigabit Ethernet PHY if desired.
The reference clock may be provided by either an external clock input of 25 MHz 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 REF_SEL. Other than the crystal, no external components are
required for crystal oscillator operation. The REF_33MHz configuration pins is used to select between a 33 and 25 MHz input
frequency.
The MPC9850 is packaged in a 100 lead MAPBGA package to optimize both performance and board density.
