It operates from a 3.135 V to 3.465 V supply and draws 162 mA typical. ## Supply rails and output frequency selection The oscillator accepts a 3.135 V to 3.465 V supply rail — a 3.3 V nominal with ±5 % tolerance. The 162 mA supply current is the total draw from this rail; no external load-capacitance matching is needed because the MEMS resonator and PLL are integrated inside the 8-QFM package. The three output frequencies (400 MHz, 900 MHz, 1 GHz) are factory-programmed via the base part number suffix. The LMK61E2BBA-SIAR variant is configured for one of these frequencies — confirm the specific output on the device marking or the TI orderable configuration guide before placing the BOM line. ## Package footprint and board integration Housed in an 8-SMD module (8-QFM) measuring 7 mm × 5 mm, the LMK61E2BBA-SIAR mounts on a standard surface-mount land pattern. The exposed thermal pad on the bottom of the package should be soldered to a PCB ground plane for heat sinking and to keep the internal PLL jitter within spec. The tape-and-reel packaging supports automated pick-and-place assembly. The reel quantity is not listed here; confirm the reel count with the distributor at quote time.","metaTitle":"Texas Instruments LMK61E2BBA-SIAR Clock Oscillator, 1 GHz","metaDescription":"Texas Instruments LMK61E2BBA-SIAR clock oscillator, 400 MHz / 900 MHz / 1 GHz, 3.135-3.465 V, -40 to 85°C, 8-QFM.
