Product details

The DSC1001CI2-039.3216T is a 39.3216 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series. Supply voltage spans 1.8V to 3.3V, so the same part number works across 1.8V, 2.5V, and 3.3V logic rails — no need to qualify a different oscillator for each voltage domain.

Standby power-down and low active current

When the standby (power-down) function is asserted, the oscillator drops to 15 µA maximum disable current — negligible for battery-backed real-time clocks or wake-up receivers that need to preserve a coin cell.

Package, footprint, and storage

Housed in a no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. Supplied on Tape & Reel (TR) — store reels in a dry cabinet if the MSL level is not confirmed.

Frequently asked questions

Is DSC1001CI2-039.3216T AEC-Q100 qualified?

Yes, the DSC1001CI2-039.3216T carries an AEC-Q100 rating, which means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up. It is suitable for under-hood and cabin electronics where the ambient temperature reaches -40°C to +85°C.

What is the standby power consumption of DSC1001CI2-039.3216T?

When the standby (power-down) function is enabled, the maximum disable current is 15 µA. This is the current drawn from the supply rail when the output is disabled, making it suitable for battery-backed systems that need to preserve power during sleep modes.
