Product details

MEMS XO with 2.3 MHz to 170 MHz programmability

The DSC1101DL3-PROGT is a MEMS-based XO (Standard) oscillator from Microchip's DSC1101 series, delivering a CMOS output across a programmable frequency range of 2.3 MHz to 170 MHz. The wide supply range of 2.25V to 3.6V means it can run directly from a 3.3V or 2.5V rail without an intermediate LDO, simplifying the power tree.

Blank device — programming step required

This ordering code ships as a blank (user must program) device — the frequency is not pre-set at the factory. Your build flow must include a programming step using Microchip's TimeFlash or a compatible programmer.

New designs can proceed without a forced migration. The 6-VDFN package (2.50mm x 2.00mm footprint, 0.90mm seated height) is a surface-mount MEMS oscillator that reflows with standard lead-free profiles. The tape-and-reel (TR) and cut-tape (CT) packaging options cover both prototyping and volume assembly.

Frequently asked questions

Does the DSC1101DL3-PROGT require an external crystal?

No. The base resonator is a MEMS element integrated inside the package — there is no external crystal or load capacitor needed. The device generates the output clock from its internal MEMS resonator.

Can the DSC1101DL3-PROGT replace a fixed-frequency oscillator in my design?

Yes, if the fixed-frequency oscillator is a CMOS-output XO in a similar 6-VDFN footprint and operates within the 2.25V to 3.6V supply range. The DSC1101DL3-PROGT is blank, so you program it to the exact frequency your BOM requires — this can consolidate multiple fixed-frequency line items into one programmable part number.

What is the programming procedure for the DSC1101DL3-PROGT?

Microchip provides the TimeFlash programming tool and software to set the output frequency, pull range, and other configuration options. The blank device is programmed in-system or on a programming fixture before assembly. Refer to the DSC1101 series datasheet for the specific register map and programming sequence.
