100 MHz fixed-frequency oscillator for timing-critical designs
The Texas Instruments LMK62E2-100M00SIAT is a 100 MHz clock oscillator in a 6-SMD module (6-QFM, 7x5 mm). It belongs to the LMK62E2 family of fixed-frequency oscillators designed for systems that need a clean, stable reference clock without external tuning components. The supply voltage tolerance covers 3.3 V nominal rails with ±5% margin, which means it stays in spec even on a noisy board where the 3.3 V rail droops under load.
The 6-QFM (7x5 mm) package is a surface-mount module with an exposed pad for thermal conduction. The 6-SMD footprint is common across the LMK62E2 family, so a single PCB layout serves multiple frequency variants if the BOM changes.
The base product number LMK62E2 covers the family, and the suffix encodes the frequency and package variant — ordering the exact suffix avoids a frequency mismatch on the board.
