Functional Description
The MPC93R52 is a fully 3.3V compatible PLL clock generator and
clock driver. The device has the capability to generate output clock
signals of 16.67 to 240 MHz from external clock sources. The internal PLL
optimized for its frequency range and does not require external look filter
components. One output of the MPC93R52 has to be connected to the
PLL feedback input FB_IN to close the external PLL feedback path. The
output divider of this output setting determines the PLL frequency
multiplication factor. This multiplication factor, F_RANGE and the
reference clock frequency must be selected to situate the VCO in its
specified lock range. The frequency of the clock outputs can be
configured individually for all three output banks by the FSELx pins
supporting systems with different but phase-aligned clock frequencies.

CASE 873A
The PLL of the MPC93R52 minimizes the propagation delay and therefore supports zero-delay applications. All inputs and
outputs are LVCMOS compatible. The outputs are optimized to drive parallel terminated 50Ω transmission lines. Alternatively,
each output can drive up to two series terminated transmission lines giving the device an effective fanout of 22.
The device also supports output high-impedance disable and a PLL bypass mode for static system test and diagnosis. The
MPC93R52 is package in a 32 ld LQFP.
