MPC950

Low Voltage PLL Clock Driver

The MPC950 is a 3.3V compatible, PLL based clock driver device

targeted for high performance clock tree designs. With output frequencies

of up to 180MHz and output skews of 375ps the MPC950 is ideal for the

most demanding clock tree designs. The devices employ a fully

differential PLL design to minimize cycle–to–cycle and long term jitter.

This parameter is of significant importance when the clock driver is

providing the reference clock for PLL’s on board today’s microprocessors

and ASiC’s. The devices offer 9 low skew outputs, the outputs are

configurable to support the clocking needs of the various high

performance microprocessors.

Microprocessors

• LQFP Packaging

• Output Frequency Configurable

• ±100ps Typical Cycle–to–Cycle Jitter

Two selectable feedback division ratios are available on the MPC950

to provide input reference clock flexibility. The FBSEL pin will choose

between a divide by 8 or a divide by 16 of the VCO frequency to be

compared with the input reference to the MPC950. The internal VCO is

running at either 2x or 4x the high speed output, depending on

configuration, so that the input reference will be either one half, one fourth

or one eighth the high speed output.

The MPC950 provides an external test clock input for scan clock distribution or system diagnostics. In addition the REF_SEL

pin allows the user to select between a crystal input to an on–board oscillator for the reference or to chose a TTL level oscillator

input directly. The on–board crystal oscillator requires no external components beyond a series resonant crystal.

The MPC950 is fully 3.3V compatible and require no external loop filter components. All inputs accept LVCMOS or LVTTL

compatible levels while the outputs provide LVCMOS levels with the capability to drive terminated 50Ω transmission lines. Select

inputs do not have internal pull–up/pull–down resistors and thus must be set externally. For series terminated 50Ω lines, each of

the MPC950 outputs can drive two traces giving the device an effective fanout of 1:18. The device is packaged in a 7x7mm

32–lead LQFP package to provide the optimum combination of board density and performance.
