Housed in a 6-QFM (7x5) package, it operates from a 3.135 V to 3.465 V supply rail and draws 162 mA typical. Supplied in Tape & Reel (TR) packaging, consistent with high-volume pick-and-place assembly. The 6-QFM (7x5) surface-mount module has a 7 mm × 5 mm footprint — a compact outline that fits into the same land pattern as standard 7×5 mm clock oscillators, easing layout reuse.","metaTitle":"Texas Instruments LMK61E0-155M52SIAR Clock Oscillator","metaDescription":"Texas Instruments LMK61E0-155M52SIAR clock oscillator, 155.52 MHz, 6-QFM, active production.
