CDCE949PW TI Clock Generator | 24-TSSOP | 4 PLL, 9 Outputs, 2.5V/3.3V

Product Overview

The CDCE949PW from Texas Instruments is a high-performance, programmable clock synthesizer and jitter cleaner designed for demanding applications. It features four independent PLL stages, each capable of generating up to nine differential or LVCMOS outputs. The device supports input frequencies from 1 MHz to 250 MHz and output frequencies up to 800 MHz, with ultra-low jitter performance (0.2 ps RMS typical). Operating from a 2.5V or 3.3V supply, it integrates on-chip voltage-controlled oscillators (VCOs) and loop filters, reducing external component count. The CDCE949PW is housed in a compact 24-pin TSSOP package, making it ideal for space-constrained designs.
