Product details

The DSC6001CI1A-003.6864 is a MEMS-based XO (Standard) from Microchip's DSC60XX series, delivering a fixed 3.6864 MHz CMOS output — a common clock frequency for CAN controllers, USB full-speed, and low-speed UART baud-rate generation.

Microchip lists this part as Obsolete. The DSC60XX series continues with other frequency variants, but this specific 3.6864 MHz code is discontinued. No last-time-buy window remains; stock is what exists in the channel. Date-code provenance and condition are verified before shipment.

1.71V–3.63V supply, CMOS output, standby function

Operates from a single 1.71V to 3.63V supply rail — compatible with 1.8V, 2.5V, and 3.3V logic domains without an external level translator. Housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — the same footprint as many quartz XOs, simplifying a drop-in replacement on existing PCB layouts.

Frequently asked questions

Is the DSC6001CI1A-003.6864 AEC-Q100 qualified?

Yes — it carries AEC-Q100 ratings, meaning it passed automotive-grade reliability testing for temperature, ESD, and lifetime stress. Suitable for under-hood and cabin applications within the -40°C to +85°C range.

What is the frequency stability of the DSC6001CI1A-003.6864?

Rated at ±50 ppm over the full -40°C to +85°C temperature range. This includes initial tolerance, temperature drift, and aging — adequate for CAN, USB full-speed, and low-speed UART clocking.

What is the output type of the DSC6001CI1A-003.6864?

CMOS output — it drives standard digital loads directly and supports a Standby (Power Down) function that disables the output and reduces supply current.
