The DSC1101CM1-075.0000T is a Microchip MEMS-based XO (Standard) oscillator delivering a 75 MHz CMOS output with ±50 ppm frequency stability across the full -55°C to 125°C military temperature range. This means it keeps timing within 50 ppm from a cold-soaked avionics bay to a downhole tool at 125°C — something a quartz XO would struggle with without an oven.
Standby mode and supply flexibility
The supply voltage range of 2.25V to 3.6V covers common 2.5V and 3.3V rails without an external regulator.
No last-time-buy window is in effect, and the part remains available for new designs.
6-SMD no-lead footprint
Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The compact footprint suits space-constrained PCBs in portable or multi-layer designs, and the no-lead construction reduces parasitic inductance compared to a leaded package.
