29.4912 MHz MEMS oscillator for wide-temperature timing
The DSC1121AM1-029.4912 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a 29.4912 MHz CMOS output with ±50ppm frequency stability across the full -55°C to 125°C military temperature range. Supply voltage spans 2.25V to 3.6V, making it compatible with 2.5V and 3.3V logic rails without an external regulator.
Package and board-fit details
Housed in a 6-VDFN with exposed pad (7.00mm x 5.00mm footprint, 0.90mm seated height), the DSC1121AM1-029.4912 is a surface-mount oscillator that requires a thermal pad on the PCB for heat dissipation — the exposed paddle should be soldered to a ground plane to keep junction temperature within the MIL-temp rating.
No minimum order quantity beyond standard reel increments.
