Product Summary

The CDCE949 is a modular PLL-based low-cost, high-performance, programmable clock synthesizer, multiplier, and divider. It generates up to 3 output clocks from a single input frequency. Each output can be programmed in-system for any clock frequency up to 230 MHz, using the integrated configurable PLL. The applications of the CDCE949 include: D-TV, STB, IP-STB, DVD-Player, DVD-Recorder, Printer and general purpose frequency sythesizing.
