Product details

The DSC1001AI2-148.5000T is a Microchip MEMS-based XO (standard) delivering a 148.5 MHz CMOS clock output from a 1.8V to 3.3V supply rail. This is the same qualification level used for under-hood ECUs and ADAS camera modules.

The 4-SMD, no-lead exposed-pad package (7.00mm x 5.00mm, 0.90mm seated height) is a standard 7x5 ceramic oscillator footprint. Supplied in tape and reel (TR), compatible with high-speed pick-and-place. The 0.90mm height keeps it within the clearance envelope for mezzanine card and blade server applications.

Frequently asked questions

How can I order the DSC1001AI2-148.5000T or request a quote?

The DSC1001AI2-148.5000T is an active-production part. Submit an RFQ through this page for current pricing and lead-time confirmation.

What is the frequency stability of the DSC1001AI2-148.5000T?

This is the total stability including temperature, supply voltage, and aging, so it defines the worst-case clock accuracy in the system.

Is the DSC1001AI2-148.5000T AEC-Q100 qualified?

Yes, the DSC1001AI2-148.5000T is AEC-Q100 qualified. This means it has passed automotive-grade reliability testing (temperature cycling, ESD, latch-up) and supports PPAP documentation for automotive BOMs.

Does the DSC1001AI2-148.5000T support a standby power-down function?

Yes, the part includes a standby (power-down) function that disables the output and reduces supply current to 15 µA max.
