Product details

Supply voltage and interface compatibility

Operating from 1.7V to 3.6V, the oscillator covers 1.8V, 2.5V, and 3.3V logic rails without an external regulator — one BOM entry serves multiple core voltages. The CMOS output interfaces directly with most MCU clock inputs, FPGA clock pins, and Ethernet PHY reference oscillators; no level translation needed when the supply matches the receiving rail.

Package footprint and layout notes

Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the part fits tight PCB stack-ups in automotive ECUs and portable instrumentation.

No last-time-buy window or successor part has been announced.

Frequently asked questions

What is the frequency stability of DSC1001CL2-066.0000?

The frequency stability is ±25 ppm over the operating temperature range and supply voltage variation.

Is DSC1001CL2-066.0000 compatible with a 1.8V supply?

Yes. The supply voltage range is 1.7V to 3.6V, so a 1.8V rail is within spec. The CMOS output swings rail-to-rail, matching the receiving logic level.

Is DSC1001CL2-066.0000 AEC-Q100 qualified?

Yes, it carries AEC-Q100 qualification, making it suitable for automotive applications where reliability testing per the standard is required.
