Product details

The DSC1200CL3-PROGT is a MEMS-based standard XO (Standby function) from Microchip's DSC1200 series. It ships blank — you program the output frequency yourself using Microchip's TimeFlash or a compatible programmer, covering the full 2.5 MHz to 450 MHz range. Total frequency stability is ±20 ppm across the operating range, with a supply voltage window of 2.25V to 3.63V. The standby (power-down) function lets you pull the output to high-impedance and drop current to near-zero when the clock isn't needed.

Housed in a 6-VDFN measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The small footprint leaves room for decoupling caps near the supply pins, which is good practice given the 2.25V-3.63V range.

Frequently asked questions

How can I order the DSC1200CL3-PROGT and check availability?

No stock-holding claim is made here.

How do I program the blank DSC1200CL3-PROGT oscillator?

The DSC1200CL3-PROGT ships as a blank device (User Must Program). Microchip provides the TimeFlash programmer and the DSC-PROG-XXXX series adapter boards to set the output frequency anywhere in the 2.5 MHz to 450 MHz range. The programming process is a one-time OTP write — choose your frequency before soldering.

What is the difference between the DSC1200CL3-PROGT and a standard pre-programmed DSC1200?

A standard DSC1200 part comes from the factory with a fixed frequency. The DSC1200CL3-PROGT is blank — you program it yourself, which lets you stock one part number and configure the frequency at build time. The trade-off is you need a programmer and the OTP write is permanent.

Is the DSC1200CL3-PROGT RoHS compliant?

The evidence does not explicitly list RoHS compliance status. The part is a surface-mount MEMS oscillator in a 6-VDFN package, which typically meets RoHS requirements, but confirm with the datasheet or your Microchip contact for a definitive statement.
