Product details

The DSC1101AI5-019.4400T is a MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a 19.44 MHz CMOS output with ±10 ppm frequency stability across -40°C to 85°C — a fit for industrial control, outdoor telecom, and factory-floor equipment where quartz oscillators may drift under vibration or temperature cycling.

Supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an external regulator — one less BOM line for a mixed-voltage board.

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — the exposed pad under the package provides a thermal path to the PCB ground plane; a via array under the pad improves heat spreading if the oscillator sits near a hot regulator or processor.

Sourced through independent distribution against the BOM quantity.

Frequently asked questions

What is the standby power consumption of DSC1101AI5-019.4400T?

In standby (power-down) mode, the supply current is 95 µA max. This is low enough to keep the oscillator's draw below the deep-sleep current of most MCUs, making it suitable for battery-powered designs that cycle between active and sleep states.
