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.
Features
5 LVCMOS outputs for processor and other system circuitry
3 Buffered 25-MHz reference clock outputs
Crystal oscillator or external reference input
25-MHz input reference frequency
Selectable output frequencies include: 66, 100, 125, or 133 MHz
Low cycle-to-cycle and period jitter
Package: 20-lead SSOP
3.3-V supply
Supports computing, networking, and telecommunications applications
Ambient temperature range: –40°C to +85°C
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.
