Product details

The DSC1001AI1-014.3181T is a MEMS-based XO (standard) oscillator from Microchip's DSC1001 series, delivering a 14.3181 MHz CMOS output with ±50 ppm frequency stability.

The supply voltage range spans 1.8 V to 3.3 V, covering common digital rails without needing a separate regulator. Active draw is 6.3 mA max, dropping to 15 µA in standby (power-down mode) — the standby function lets the system gate the oscillator when the clock tree is idle, cutting quiescent load on the battery or supply.

Housed in a 4-SMD, no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1001AI1-014.3181T is a surface-mount device supplied on tape and reel.

Frequently asked questions

Is DSC1001AI1-014.3181T drop-in compatible with standard 14.31818 MHz quartz oscillators?

Functionally yes — it outputs a 14.3181 MHz CMOS signal at the same frequency used in video timing and legacy serial interfaces. However, the package is a 7.00 mm x 5.00 mm 4-SMD no-lead exposed pad, which differs from the common 5.00 mm x 3.20 mm quartz oscillator footprint. Verify the PCB land pattern before substituting.

What supply voltage range does DSC1001AI1-014.3181T support?

The DSC1001AI1-014.3181T operates from 1.8 V to 3.3 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator.
