Product details

Programmable MEMS oscillator for multi-frequency BOM consolidation

The DSC1200CL3-PROG is a blank-programmable MEMS XO from Microchip's DSC1200 series, covering 2.5 MHz to 450 MHz in a single part number. You program the output frequency after procurement, which means one line item can serve multiple clock rates across a design — useful when a single PCB variant ships with different processor speeds or interface bit rates.

Supply voltage tolerance and standby function

Operates from 2.25 V to 3.63 V supply — compatible with 2.5 V, 3.0 V, and 3.3 V logic rails without a separate level translator.

Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. Surface-mount assembly with standard reflow; no underfill needed for typical industrial vibration levels.

Frequently asked questions

How do I program the DSC1200CL3-PROG?

The DSC1200CL3-PROG is shipped blank — you must program the output frequency using Microchip's TimeFlash field programming kit or a compatible in-system programmer. Microchip provides a free software tool (TimeFlash GUI) that generates the programming file; the programming itself takes a few seconds per device. Plan for a programming step in your assembly flow.

Can DSC1200CL3-PROG replace a fixed-frequency oscillator?

Yes, if the fixed oscillator is a standard 2.5 V to 3.63 V MEMS or quartz XO in a 6-VDFN or compatible footprint. The DSC1200CL3-PROG can be programmed to any frequency within 2.5 MHz to 450 MHz, so it can replace multiple fixed-frequency parts with one programmable SKU. Verify the output drive strength and load capacitance match the downstream receiver's input threshold.

What is the closest pin-compatible alternative in the DSC1200 family?

Within the DSC1200 series, the pre-programmed fixed-frequency variants (e.g., DSC1200CL3-xxx.xxxx) share the same 6-VDFN package and pinout. The difference is that those ship with a factory-set frequency, while the PROG version is blank. If you need a drop-in replacement without programming, order the fixed-frequency variant at your target frequency.
