DESCRIPTION

· The CDCE925 and CDCEL925 are modular PLL-based, low-cost, high-performance, programmable clock synthesizers, multipliers, and dividers.

· They generate up to five output clocks from a single input frequency.

· Each output can be programmed in-system for any clock frequency up to 230MHz, using up to two independent configurable PLLs.

· The CDCEx925 has a separate output supply pin, VDDOUT, which is 1.8V for CDCEL925 and 2.5V to 3.3V for CDCE925.

· The input accepts an external crystal or LVCMOS clock signal.

· In case of a crystal input, 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.
