2013 Integrated Device Technology, Inc.
The MPC9315 is a 2.5 V and 3.3 V compatible, PLL based clock generator
designed for low-skew clock distribution in low-voltage mid-range to
high-performance telecom, networking and computing applications. The
MPC9315 offers 8 low-skew outputs and 2 selectable inputs for clock
redundancy. The outputs are configurable and support 1:1, 2:1, 4:1, 1:2 and 1:4
output to input frequency ratios. In addition, a selectable output 180
phase
control supports advanced clocking schemes with inverted clock signals. The
MPC9315 is specified for the extended temperature range of –40 to +85
C.

Functional Description
The MPC9315 utilizes PLL technology to frequency and phase lock its outputs onto an input reference clock. Normal operation
requires a connection of one of the device outputs to the selected feedback (FB0 or FB1) input to close the PLL feedback path.
The reference clock frequency and the output divider for the feedback path determine the VCO frequency. Both must be selected
to match the VCO frequency range. With available output dividers of divide-by-1, divide-by-2 and divide-by-4, the internal VCO
of the MPC9315 is running at either 1x, 2x or 4x of the reference clock frequency. The frequency of the QA, QB, QC output groups
is either the equal, one half or one fourth of the selected VCO frequency and can be configured for each output bank using the
FSELA, FSELB and FSELC pins, respectively. The available output to input frequency ratios are 4:1, 2:1, 1:1, 1:2 and 1:4. The
REF_SEL pin selects one of the two available LVCMOS compatible reference input (CLK0 and CLK1) supporting clock redundant
applications. The selectable feedback input pin allows the user to select different feedback configurations and input to output
frequency ratios. The MPC9315 also provides a static test mode when the PLL supply pin (VCCA) is pulled to logic low state
(GND). In test mode, the selected input reference clock is routed directly to the output dividers bypassing the PLL. The test mode
is intended for system diagnostics, test and debug purposes. This test mode is fully static and the minimum clock frequency spec-
ification does not apply. The outputs can be disabled by deasserting the OE pin (logic high state). In PLL mode, deasserting OE
causes the PLL to lose lock due to no feedback signal presence at FB0 or FB1. Asserting OE will enable the outputs and close
the phase locked loop, also enabling the PLL to recover to normal operation. The MPC9315 is fully 2.5 V and 3.3 V compatible
and requires no external loop filter components. All inputs accept LVCMOS signals while the outputs provide LVCMOS compat-
ible levels with the capability to drive terminated 50
transmission lines. For series terminated transmission lines, each of the
MPC9315 outputs can drive one or two traces giving the devices an effective fanout of 1:18. The device is packaged in a 7x7 mm2
32-lead LQFP package.
The fully integrated PLL of the MPC9315 allows the low skew outputs to lock onto a clock input and distribute it with essentially
zero propagation delay to multiple components on the board. In zero-delay buffer mode, the PLL minimizes phase offset between
the outputs and the reference signal.
