3.3V 1:6 LVCMOS PLL Clock
Generator
The MPC9330 is a 3.3V compatible, 1:6 PLL based clock generator
targeted for high performance low-skew clock distribution in mid-range to
high-performance telecomm, networking and computing applications.
With output frequencies up to 120 MHz and output skews less than 150ps
the device meets the needs of the most demanding clock applications.
The MPC9330 is specified for the temperature range of 0
°C to +70°C.

Functional Description
The MPC9330 utilizes PLL technology to frequency lock its outputs onto an input reference clock. Normal operation of the
MPC9330 requires either the selection of internal PLL feedback or the connection of one of the device outputs to the feedback
input to close the PLL feedback path in external feedback mode. The reference clock frequency and the divider for the feedback
path determine the VCO frequency. Both must be selected to match the VCO frequency range. In external PLL feedback
configuration and with the available post-PLL dividers (divide-by-2, divide-by-4 and divide-by-6), the internal VCO of the
MPC9330 is running at either 4x, 8x, 12x, 16x or 24x of the reference clock frequency. In internal feedback configuration (divide-
by-16) the internal VCO is running 16x of the reference frequency. The frequency of the QA, QB, QC output banks is a division of
the VCO frequency and can be configured independently for each output bank using the FSELA, FSELB and FSELC pins,
respectively. The available output to input frequency ratios are 4x, 3x, 2x, 1x, 4/3x, 3/2x, 2/3x, x/2, x/3 or x/4.
The REF_SEL pin selects the internal crystal oscillator or the LVCMOS compatible input as the reference clock signal. The
PLL_EN control selects the PLL bypass configuration for test and diagnosis. In this configuration, the selected input reference
clock is routed directly to the output dividers bypassing the PLL. The PLL bypass is fully static and the minimum clock frequency
specification and all other PLL characteristics do not apply.
The outputs can be disabled (high-impedance) by deasserting the OE/MR pin. In the PLL configuration with external feedback
selected, deasserting OE/MR causes the PLL to loose lock due to missing feedback signal presence at FB_IN. Asserting OE/MR
will enable the outputs and close the phase locked loop, enabling the PLL to recover to normal operation. The MPC9330 output
clock stop control allows the outputs to start and stop synchronously in the logic low state, without the potential generation of runt
pulses.
The MPC9330 is fully 3.3V compatible and requires no external loop filter components. All inputs (except XTAL) accept
LVCMOS signals while the outputs provide LVCMOS compatible levels with the capability to drive terminated 50
W transmission
lines. For series terminated transmission lines, each of the MPC9330 outputs can drive one or two traces giving the devices an
effective fanout of 1:12. The device is packaged in a 7x7 mm2 32-lead LQFP package.
