Product Summary

The CDCE937 is a modular PLL-based low-cost, high-performance, programmable clock synthesizer, multiplier, and divider. The CDCE937 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 CDCE937 has separate output supply pins, V DDOUT , which is 1.8 V for CDCEL913 and 2.5 V to 3.3 V for CDCE913. The applications of the device include D-TV, STB, IP-STB, DVD-Player, DVD-Recorder, Printer.
