LMK05028RGCT TI Clock Generator | 64-VQFN (9x9) | 2 PLL, 14 Outputs, 0.2ps RMS Jitter

Product Overview

The LMK05028RGCT is a high-performance clock generator from Texas Instruments, designed for demanding applications requiring ultra-low jitter and flexible frequency synthesis. Housed in a compact 64-VQFN (9x9 mm) package, it integrates two independent phase-locked loops (PLLs) with voltage-controlled oscillators (VCOs) to generate up to 14 differential or LVCMOS clock outputs. The device supports frequencies from 1 Hz to 2.5 GHz, with typical RMS jitter as low as 0.2 ps (12 kHz to 20 MHz). It operates from a single 3.3V supply and includes advanced features like hitless reference switching, digital holdover, and programmable loop bandwidth.
