The standby (power-down) function lets the host MCU gate the oscillator output and draw only 15 µA maximum while the part is disabled, versus 16 mA active — important for power-cycling strategies in battery-hosted or wake-on-event firmware. ## Frequency stability across temperature ±10 ppm across -40 °C to 105 °C operating temperature covers industrial ambient ranges without requiring a TCXO for many applications — for a UART at 115200 baud, ±10 ppm contributes well under one baud error at room temperature, and stays within specification across the full operating band. ## Package, board fit, and rework The exposed pad also means rework requires pre-bake to prevent delamination, and the absence of side terminations reduces tombstoning risk during reflow compared to leaded equivalents — but visual inspection of the solder joint under the pad is not possible without X-ray. ## Sourcing and lifecycle Quoted to order against BOM quantity through independent distribution; availability and current lead times confirmed at RFQ.","metaTitle":"ASVMB-29.4912MHZ-XY-T Abracon XO, 29.4912 MHz, ±10ppm","metaDescription":"Abracon ASVMB-29.4912MHZ-XY-T: MEMS XO, 29.4912 MHz, LVCMOS, ±10ppm, -40°C to 105°C, 1.8-3.3V supply, 4-SMD.
