Product details

The DSC1201CA3-PROG is a MEMS-based XO (Standard) oscillator from Microchip's DSC12X1 series, delivering a CMOS output across a programmable frequency range of 2.5 MHz to 170 MHz. The 6-VDFN package (3.20 mm x 2.50 mm, 0.90 mm seated height) fits tight PCB layouts and supports reflow assembly with standard surface-mount processes.

User-programmable blank — production flow impact

This part ships as a blank device (user-programmable) — it requires programming before it outputs a clock. That means your production line needs a programming step, either via Microchip's TimeFlash or a third-party programmer, before pick-and-place.

Frequently asked questions

How do I program the DSC1201CA3-PROG oscillator?

The DSC1201CA3-PROG is a blank device that must be programmed with the desired output frequency before use. Microchip provides the TimeFlash programming tool and software; third-party programmers supporting the DSC12X1 family also work. The programming step can be done in-house or by a programming service before the oscillator is placed on the board.

Is DSC1201CA3-PROG compliant with AEC-Q100?

Yes, the DSC1201CA3-PROG is rated AEC-Q100, meaning it has passed automotive-grade qualification for temperature, reliability, and quality.

Can I use DSC1201CA3-PROG as a replacement for standard quartz oscillators?

Yes, it is a drop-in replacement for many quartz XO oscillators in the same 6-VDFN footprint and CMOS output. The MEMS resonator is more resistant to vibration and shock than quartz, and the programmable frequency range (2.5 MHz to 170 MHz) covers common MCU and interface clock speeds. Confirm the supply voltage and pinout match your existing oscillator before substituting.

Does DSC1201CA3-PROG require external programming hardware?

Yes, because it ships blank. You need a programmer compatible with Microchip's DSC12X1 family — the TimeFlash tool is the manufacturer's recommended option. The programming hardware connects to the oscillator's I2C interface to set the output frequency.
