The MPC9658 is a 3.3 V compatible, 1:10 PLL based clock generator and
zero-delay buffer targeted for high performance low-skew clock distribution in
mid-range to high-performance telecom, networking and computing applications.
With output frequencies up to 250 MHz and output skews less than 120 ps the
device meets the needs of the most demanding clock applications. The
MPC9658 is specified for the temperature range of 0°C to +70°C.

The MPC9658 utilizes PLL technology to frequency lock its outputs onto an
input reference clock. Normal operation of the MPC9658 requires the connection
of the QFB output to the feedback input to close the PLL feedback path (external
feedback). With the PLL locked, the output frequency is equal to the reference
frequency of the device and VCO_SEL selects the operating frequency range of
50 to 125 MHz or 100 to 250 MHz. The two available post-PLL dividers selected
by VCO_SEL (divide-by-2 or divide-by-4) and the reference clock frequency determine the VCO frequency. Both must be select-
ed to match the VCO frequency range. The internal VCO of the MPC9658 is running at either 2x or 4x of the reference clock
frequency.
The MPC9658 has a differential LVPECL reference input along with an external feedback input. The MPC9658 is ideal for use
as a zero delay, low skew fanout buffer. The device performance has been tuned and optimized for zero delay performance.
The PLL_EN and BYPASS controls select the PLL bypass configuration for test and diagnosis. In this configuration, the se-
lected input reference clock is bypassing the PLL and routed either to the output dividers or directly to the outputs. The PLL by-
pass configurations are fully static and the minimum clock frequency specification and all other PLL characteristics do not apply.
The outputs can be disabled (high-impedance) and the device reset by asserting the MR/OE pin. Asserting MR/OE also causes
the PLL to loose lock due to missing feedback signal presence at FB_IN. Deasserting MR/OE will enable the outputs and close
the phase locked loop, enabling the PLL to recover to normal operation.
The MPC9658 is fully 3.3 V compatible and requires no external loop filter components. The inputs (except PCLK) accept
LVCMOS except signals while the outputs provide LVCMOS compatible levels with the capability to drive terminated 50
trans-
mission lines. For series terminated transmission lines, each of the MPC9658 outputs can drive one or two traces giving the de-
vices an effective fanout of 1:16. The device is packaged in a 7x7 mm2 32-lead LQFP package.
