Clock Generator for PowerQUICC
and PowerPC Microprocessors and
Microcontrollers
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, 166 and
200 MHz. The device offers five 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.
Features
6 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 = 33, 50, 66, 100, 125, 133, 166, or 200 MHz
Low cycle-to-cycle and period jitter
Package = 32 lead LQFP
3.3 V supply
Supports computing, networking, telecommunications applications
Ambient temperature range -40°C to +85°C
Functional Description
The MPC9824 uses a PLL with a 25 MHz input reference frequency to generate a single bank of 5 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 my 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.
