The MPC9824 is a PLL based clock generator specifically designed for

Freescale Microprocessor and Microcontroller applications including the

PowerPC and PowerQUICC. This device generates the microprocessor input

clock and other microprocessor system and bus clocks at any one of eight output

frequencies. These frequencies include 33, 50, 66, 100, 125, 133.33, 166.66 and

200 MHz. The device offers six low skew clock outputs plus the three reference

outputs. The clock input reference is 25 MHz and may be derived from an

external source of by the addition of a 25 MHz crystal to the on-chip crystal

oscillator. The extended temperature range of the MPC9824 supports

telecommunication and networking requirements.

Functional Description

The MPC9824 uses a PLL with a 25 MHz input reference frequency to generate a single bank of 6 configurable LVCMOS

output clocks. The output frequency of this bank is configurable by three FSEL pins. The 25 MHz reference may be either an

external frequency source or a 25 MHz crystal. The 25 MHz crystal is directly connected to the XTAL_IN and XTAL_OUT pins

with no additional components required. An external reference may be applied to the XTAL_IN pin with the XTAL_OUT pin left

floating. The input reference, whether provided by a crystal or an external input is also directly buffered to a second bank of

3 LVCMOS outputs. These outputs may be used as the clock source for processor I/O applications such as an Ethernet PHY.

The MPC9824 is packaged in a 32 lead LQFP package.
