Product details

The wide 1.8V to 3.3V supply range lets it run directly off a 3.3V rail or a 1.8V core supply without a level translator.

An engine ECU sitting at 105°C on a hot day still has margin before the part's absolute maximum junction temperature — the MEMS die doesn't drift like a quartz AT-cut does over that span. The 4-SMD, No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3225 footprint that reflows with a typical lead-free profile. No special bake-out or moisture sensitivity level (MSL) handling beyond the standard JEDEC floor life.

The base product number DSC1001 covers the family; the full order code DSC1001CL5-020.0000T encodes the specific frequency, stability grade, and temperature range.

Frequently asked questions

Is the DSC1001CL5-020.0000T RoHS compliant?

The evidence does not list a specific RoHS status, but Microchip's DSC1001 series is typically RoHS-compliant and lead-free. Confirm the specific date-code compliance against your local RoHS exemption requirements at order time.

What is the closest pin-compatible alternative to the DSC1001CL5-020.0000T in the same family?

Within the DSC1001 series, other frequency and stability variants share the same 4-SMD, No Lead footprint and supply voltage range. For a direct 20 MHz replacement with different stability (±25 ppm or ±50 ppm), look at the DSC1001CL2-020.0000T or DSC1001CL1-020.0000T — same package, same pinout, same AEC-Q100 rating.

What output type does the DSC1001CL5-020.0000T provide?

CMOS output — a standard rail-to-rail digital clock signal that interfaces directly with MCU clock inputs, FPGA clock pins, and most logic families without external level translation.
