Description

General part information

CDCEL937 Series

The CDCE937 and CDCEL937 devices are modular PLL-based low cost, high-performance, programmable clock synthesizers, multipliers and dividers. The devices generate up to 7 output clocks from a single input frequency. Each output can be programmed in-system for any clock frequency up to 230MHz, using up to three independent configurable PLLs.

The CDCEx937 has separate output supply pins, VDDOUT, which is 1.8V for CDCEL937 and to 2.5V to 3.3V for CDCE937.

The input accepts an external crystal or LVCMOS clock signal. If an external crystal is used, an on-chip load capacitor is adequate for most applications. The value of the load capacitor is programmable from 0 to 20pF. Additionally, an on-chip VCXO is selectable which allows synchronization of the output frequency to an external control signal, that is, PWM signal.
