The MPC97H73 is a 3.3V compatible, 1:12 PLL based clock generator

targeted for high performance low-skew clock distribution in mid-range to

high-performance networking, computing and telecom applications. With

output frequencies up to 240 MHz and output skews less than 250 ps the

device meets the needs of the most demanding clock applications.

Functional Description

The MPC97H73 utilizes PLL technology to frequency lock its outputs onto an input reference clock. Normal operation of the

MPC97H73 requires the connection of the PLL feedback output QFB to feedback input FB_IN to close the PLL feedback path.

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. The MPC97H73 features an extensive level of frequency programmability between the 12

outputs as well as the output to input relationships, for instance 1:1, 2:1, 3:1, 3:2, 4:1, 4:3, 5:1, 5:2, 5:3, 5:4, 5:6, 6:1, 8:1 and 8:3.

The QSYNC output will indicate when the coincident rising edges of the above relationships will occur. The selectability of the

feedback frequency is independent of the output frequencies. This allows for very flexible programming of the input reference

versus output frequency relationship. The output frequencies can be either odd or even multiples of the input reference. In

addition the output frequency can be less than the input frequency for applications where a frequency needs to be reduced by a

non–binary factor. The MPC97H73 also supports the 180° phase shift of one of its output banks with respect to the other output

banks. The QSYNC outputs reflects the phase relationship between the QA and QC outputs and can be used for the generation

of system baseline timing signals.

The REF_SEL pin selects the LVPECL or the LVCMOS compatible inputs as the reference clock signal. Two alternative

LVCMOS compatible clock inputs are provided for clock redundancy support. 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 individually disabled (stopped in logic low state) by programming the serial CLOCK_STOP interface of the

MPC97H73. The MPC97H73 has an internal power–on reset.

The MPC97H73 is fully 3.3V compatible and requires no external loop filter components. All inputs (except PCLK) 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 MPC97H73 outputs can drive one or two traces giving the devices an

effective fanout of 1:24. The device is pin and function compatible to the MPC973 and is packaged in a 52-lead LQFP package.
