LMK5C22212ARGCT TI Clock Generator | 64-VQFN (9x9) | 12 Outputs, Jitter < 100 fs

Product Overview

The LMK5C22212ARGCT is a high-performance clock generator from Texas Instruments, designed for demanding applications requiring ultra-low jitter and multiple output frequencies. Housed in a compact 64-VQFN (9x9 mm) package, this device integrates a fractional-N PLL with VCO to generate up to 12 differential or 24 single-ended clock outputs. It supports frequencies from 1 Hz to 1 GHz, with typical RMS jitter below 100 fs (12 kHz–20 MHz). The device operates from a 3.3V supply and includes advanced features like hitless reference switching, digital delay, and SYSREF generation for JEDEC JESD204B/C systems.
