That second frequency is common in telecom and audio codec reference clocks — 12.288 MHz is 256× the 48 kHz audio sample rate, so it directly clocks an I2S bus or a codec PLL without an extra divider. ## ±50 ppm stability across the industrial temperature band For a 12 MHz output, that is a maximum frequency error of ±600 Hz — well within the tolerance of a UART baud-rate generator or a USB full-speed clock. The 2.25 V to 3.6 V supply range means it runs from a 3.3 V or 2.5 V rail without an external LDO. For a BOM that needs a dual-output MEMS clock, this part is a current-production choice — no last-time-buy planning required. ## 20-VFQFN package — layout notes for the exposed pad The VFQFN Exposed Pad package measures 5.00 mm × 3.20 mm with a 0.90 mm seated height.","metaTitle":"DSC400-0101Q0114KI1T MEMS XO – Dual LVCMOS Output, ±50 ppm","metaDescription":"Microchip DSC400 MEMS oscillator: dual outputs 12 MHz & 12.288 MHz, LVCMOS, ±50 ppm stability, -40 to +85 °C, 20-VFQFN.
