Product details

48 MHz MEMS XO with full military temperature range

The DSC1101CM2-048.0000T is a Microchip MEMS-based XO (Standard) delivering a 48 MHz CMOS output clock with ±25 ppm frequency stability across the full -55°C to +125°C military temperature range.

The wide supply range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V rails without an external regulator, simplifying power-tree design for mixed-voltage boards.

Supplied in tape-and-reel (TR) packaging for automated pick-and-place assembly; the 6-SMD no-lead package measures 3.20 mm × 2.50 mm × 0.90 mm, a compact footprint that frees board space in dense layouts.

Frequently asked questions

Is the DSC1101CM2-048.0000T a direct replacement for a quartz oscillator?

Functionally yes — it is a drop-in XO replacement with the same 48 MHz CMOS output and ±25 ppm stability. The MEMS resonator offers better shock and vibration tolerance than quartz, and the standby function is an added feature not always present on quartz equivalents. Verify the footprint matches your 6-SMD no-lead land pattern.

Does the DSC1101CM2-048.0000T have a standby function?

Yes — the part includes a standby (power-down) function. When enabled, the supply current drops to 95 µA max, allowing the oscillator to be gated off in low-power sleep modes without removing the supply rail.
