DescriptionThe CDCE937 and CDCEL937 devices are modular
PLL-based low cost, high-performance,
programmable clock synthesizers, multipliers and
dividers. They generate upto7 output clocks froma
single input frequency. Each output can be
programmed in-system for any clock frequency upto
230 MHz, using upto three independent configurable
PLLs.
The CDCEx937 has separate output supply pins,
VDDOUT, whichis 1.8V for CDCEL937 andto 2.5V 3.3V for CDCE937.
The input accepts an external crystalor LVCMOS
clock signal.Ifan external crystalis used, an on-chip
load capacitoris adequate for most applications. The
valueof the load capacitoris programmable from0to pF. Additionally, an on-chip VCXOis selectable
which allows synchronizationof the output frequencyan external control signal, thatis, PWM signal.
