Description
The CDCE6214TWRGERQ1 is a Texas Instruments clock management device. It’s a 4-output clock distribution/buffer that takes a reference clock (single‑ended or differential) and fans it out to four low‑jitter clock outputs. It includes an internal PLL/jitter‑cleaning mechanism and is programmable via I2C, allowing you to configure output frequencies/dividers, enable/disable individual outputs, and enter power‑down modes. The part supports multiple supply options and is suitable for clocking FPGAs, ASICs, DSPs, and other digital systems, helping to achieve low skew and clean timing across a clock tree. The suffix TWRGERQ1 indicates the Tape/Reel packaging, RoHS compliance, and related package/revision details. Typical applications include clock distribution for memory interfaces, processors, and high‑speed digital boards.
Equivalent
CDCE6214TWRGERQ1 is TI's dual-output clock distribution with jitter cleaning. There isn’t a direct one-to-one equivalent from other vendors; cross-references depend on exact specs. Comparable families include Silicon Labs Si534x jitter-cleaned clock generators; IDT 8T49N/8T49C clock-distribution families; Lattice clock-distribution devices; Analog Devices AD9528/AD9523. For an exact cross-reference, use TI’s cross-reference tool.
