Technical Data

Clock Generator for PowerQUICC

and PowerPC Microprocessors and

Microcontrollers

MPC9819

The MPC9819 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 four output

frequencies. These frequencies include the popular 66- and 133-MHz PCI/X bus

frequencies. The device offers five low-skew clock outputs plus three reference

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

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

oscillator. The extended temperature range of the MPC9819 supports

telecommunication and networking requirements.

Functional Description

The MPC9819 uses a PLL with a 25-MHz input reference frequency to generate a single bank of five configurable LVCMOS

output clocks. The output frequency of this bank is configurable to either 66, 100, 125, or 133 MHz by two 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 three LVCMOS outputs. These outputs may be used as the clock source for processor I/O

applications such as an Ethernet PHY.

The MPC9819 is packaged in a 20-lead SSOP package.
