CDCE925 Flexible Low Power LVCMOS Clock Generator

The CDCE925 and CDCEL925 are modular PLLbased 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 insystem for any clock frequency up to 230 MHz, using up to two independent configurable PLLs. The CDCEx925 has a separate out.
