Product Overview
The CDCE6214TWRGERQ1 is a high-performance clock generator from Texas Instruments, designed for automotive and industrial applications. It integrates four independent PLLs and provides up to 14 differential or LVCMOS outputs, supporting frequencies from 1 MHz to 1.5 GHz. The device operates from a single 3.3V supply and features low jitter (<0.2 ps RMS typical) and phase noise. It is housed in a compact 24-pin VQFN (4x4 mm) package, making it suitable for space-constrained designs.
