Product details

Field-programmable oscillator – what it is and who specifies it

The DSC1000AL3-PROGT is a blank (user must program) oscillator from Microchip's DSC100 series – a family of MEMS-based programmable oscillators that replace traditional quartz crystal oscillators with a silicon MEMS resonator and a programmable PLL. The 'PROGT' suffix means the device ships without a pre-programmed frequency; you load the target frequency via Microchip's programming toolchain before placing it on the board.

Package dimensions and PCB layout considerations

The 4-VDFN exposed pad package measures 7.00mm x 5.00mm with a seated height of 0.90mm. The cut tape option lets you order a few units for prototype validation before committing to a full reel.

The Tape & Reel (TR) option suits production runs; Cut Tape (CT) is available for smaller quantities during prototyping.

Frequently asked questions

How do I program the DSC1000AL3-PROGT oscillator?

The DSC1000AL3-PROGT ships as a blank device – you must program it with your target frequency using Microchip's programming toolchain (typically the TimeFlash or a compatible programmer). The programming interface is documented in the DSC1000 series datasheet; the process involves writing the frequency configuration to the device's non-volatile memory before soldering it to the PCB.

What is the closest pin-compatible alternative to the DSC1000AL3-PROGT?

Within the DSC100 series, the fixed-frequency variants (without the PROGT suffix) share the same 4-VDFN package and pinout – but they come pre-programmed from the factory. If your BOM frequency is standard and you want to skip the programming step, a fixed DSC100 part is a drop-in replacement. No other manufacturer's part is listed as a direct pin-compatible second source.
