Product details

It is part of Microchip's DSC1001 series, qualified to AEC-Q100, making it suitable for automotive ECU clock trees, CAN FD transceivers, and 100BASE-T1 Ethernet PHY reference clocks.

Supply voltage flexibility and package footprint

The 4-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm, fitting tight PCB layouts in ADAS cameras or body-control modules.

Product status is Active per Microchip's current lifecycle designation. No PPAP documentation is held on this page; request it through your Microchip channel contact.

Frequently asked questions

Can DSC1001DI1-027.0000 replace a standard 27 MHz crystal oscillator?

Yes, it can replace a standard 27 MHz crystal oscillator in most applications, provided the circuit is designed for a CMOS-level input. The MEMS-based XO outputs a rail-to-rail CMOS clock directly, eliminating the need for external load capacitors and a feedback inverter. Verify the enable/disable polarity and supply voltage compatibility with your existing design.

What is the closest pin-compatible alternative in the DSC1001 family?

The DSC1001 series includes multiple frequency variants in the same 4-VDFN package and pinout. For example, DSC1001DI1-036.0000 is a 36 MHz version with the same supply voltage range, temperature grade, and AEC-Q100 rating. Confirm the frequency and stability requirements before substituting.
