Product Overview
The CDCI6214RGET from Texas Instruments is a high-performance clock generator and jitter cleaner designed for demanding applications. It integrates four independent PLLs and 14 programmable outputs, supporting frequencies up to 1.5 GHz. The device features ultra-low jitter (<0.2 ps RMS typical) and flexible output formats including LVDS, LVPECL, HCSL, and LVCMOS. Housed in a compact 24-pin VQFN (4x4 mm) package, it is ideal for space-constrained designs.
