Texas Instruments CDCE813-Q1 Clock Synthesizer & Jitter Cleaner

Texas Instruments CDCE813-Q1 Clock Synthesizer and Jitter Cleaner is a modular Phase-Locked-Loop-based (PLL), low-cost, high-performance, programmable clock synthesizer. This device generates up to three output clocks from a single input frequency. Each output can be programmed in-system for any clock frequency up to 230MHz, using the integrated configurable PLL. The CDCE813-Q1 has separate output supply pins, VDDOUT, providing 2.5V to 3.3V. The input accepts an external crystal or LVCMOS clock signal. A selectable on-chip VCXO allows synchronization of the output frequency to an external control signal. The PLL supports SSC (spread-spectrum clocking) for better performance of electromagnetic interference (EMI).
