The DSC1121DM2-033.0000T is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 33 MHz CMOS clock with ±25 ppm frequency stability.
The 6-VDFN package (2.50 mm x 2.00 mm) is a compact surface-mount footprint; the 0.90 mm seated height keeps it low-profile for tight card stacks. Max current draw is 35 mA — budget that into the rail's total load.
Both share the same DSC1121 base number and 33 MHz frequency, but the DM2 suffix indicates the -55°C to 125°C military temperature range, while the AM2 suffix is typically a different temperature grade. Check the AM2's operating range in its datasheet — if your application stays within the AM2's limits, it may be a drop-in swap in the same 6-VDFN package. Confirm the stability and supply voltage match before committing.
±25 ppm over the full -55°C to 125°C range. That's tight enough for most Ethernet and MCU clock references without needing a TCXO.
The evidence does not explicitly list RoHS status, but Microchip's DSC1121 series is typically RoHS-compliant and lead-free. Confirm with the datasheet or your compliance team for the specific date code.
