Product details

The 1.8V to 3.3V supply range lets the same BOM entry serve 1.8V-core and 3.3V-I/O domains without a separate voltage translator or a second oscillator line item.

Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the DSC1001DI2-056.2500 fits tight board stacks and leaves room for adjacent decoupling capacitors on a dense automotive ECU layout. Surface-mount mounting with no exposed leads means the package is self-aligning during reflow; the small footprint requires a 0.50 mm pad pitch and a solder-mask-defined pad per the Microchip recommended land pattern.

Frequently asked questions

What is the closest pin-compatible alternative to the DSC1001DI2-056.2500?

The DSC1001 series includes multiple frequency and stability variants sharing the same 4-SMD no-lead footprint and pinout. For the exact 56.25 MHz frequency, the DSC1001DI2-056.2500 is the standard option; a ±25 ppm stability grade is the most common. No direct second-source from another manufacturer is listed on the evidence record.

Is the DSC1001DI2-056.2500 AEC-Q100 qualified?

Yes, the ratings field explicitly lists AEC-Q100 qualification. This means the part has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up — suitable for under-hood and chassis-domain applications.
