Product Overview
The LMK3C0105V18RERR from Texas Instruments is a high-performance clock generator designed for low-jitter, low-power applications. It operates at a 1.8V supply voltage and provides ultra-low jitter performance of 105 fs RMS (typical) in the 12 kHz to 20 MHz integration range. Housed in a compact 16-pin TQFN (3x3 mm) package, it is ideal for space-constrained designs requiring precise clocking.
