Product details

MEMS timing in a 5×3.2 mm SMD can

The DSC1001BI2-002.4576T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, outputting a 2.4576 MHz CMOS clock from a 4-SMD no-lead package measuring 5.00 mm × 3.20 mm. Runs on any supply from 1.8 V to 3.3 V, drawing 6.3 mA max while active.

Automotive temperature grade and qualification

Rated -40 to 85°C with AEC-Q100 qualification — this is the cabin-grade automotive temperature band. Suitable for infotainment, cluster, ADAS sensor modules, and telematics that see under-hood ambient but not the engine block itself. Product status is Active.

For a 2.4576 MHz clock this is tight enough for UART baud-rate generation, USB full-speed, and CAN bit timing without external trimming.

Frequently asked questions

Is DSC1001BI2-002.4576T AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating. That means it passed automotive-grade stress tests (temperature cycling, ESD, latch-up) per the JEDEC-based qualification. Use it in cabin and chassis-domain designs without a waiver.

Can DSC1001BI2-002.4576T be used as a replacement for a failed quartz oscillator?

If the original was a 2.4576 MHz CMOS-output XO in a 5.0 mm × 3.2 mm 4-pin SMD package, yes — the MEMS-based DSC1001 drops in without external load capacitors or a start-up delay. Confirm the supply voltage range (1.8-3.3 V) matches the original rail.
