It draws 162 mA typical, so a dense board with multiple oscillators needs the power budget per node, not just the core voltage rail capacity. The 6-QFM (7x5 mm) module footprint fits into the same land pattern as many 7x5 mm oscillators, simplifying a last-minute swap during BOM consolidation. ## Active lifecycle — no design-in risk This part is safe for new production builds and does not carry the obsolescence risk that forces a board respin mid-lifecycle. ## Supply voltage and power considerations The 3.135V-3.465V supply window means the oscillator runs cleanly off a 3.3V rail with ±5% tolerance — no separate LDO needed if the rail is within that band. The 162 mA supply current is the total draw from that rail; a 3.3V regulator feeding this oscillator plus other loads must budget for the peak, not just the average, to avoid dropout during transient loading.","metaTitle":"Texas Instruments LMK61E0-050M00SIAR Clock Oscillator","metaDescription":"Texas Instruments LMK61E0-050M00SIAR clock oscillator, 50 MHz fixed output, 3.3V supply, -40 to 85°C, 6-QFM package.
