Product details

MEMS timing for harsh environments

The DSC1121BM1-008.0000 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering an 8 MHz CMOS output with ±50 ppm frequency stability across the full -55°C to 125°C military temperature range. This is the oscillator you spec when the board sees thermal cycling from -55°C soak to 125°C under-hood or downhole ambient, and a quartz XO would need a separate heater or risk failing to start.

Product status is Active — no EOL notice, no last-time-buy window.

Frequently asked questions

Is the DSC1121BM1-008.0000 pin-compatible with the DSC1122 series?

The DSC1121 and DSC1122 series share the same 6-SMD no-lead package and pinout, but the DSC1122 adds a spread-spectrum modulation feature for EMI reduction. The DSC1121BM1-008.0000 does not include spread spectrum — if your design requires EMI mitigation at the clock source, the DSC1122 is the functional alternative. Pin compatibility means a single PCB layout can accept either series by changing the BOM line.
