Product details

MEMS resonator, CMOS output, user-programmed frequency

The DSC1101AL5-PROGT is a MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a CMOS output across a programmable frequency range of 2.3 MHz to 170 MHz. It is supplied as a blank device (User Must Program), meaning the output frequency is set during board-level programming — not a fixed-frequency part off the reel. Total frequency stability is ±10 ppm over the full operating range, which keeps timing jitter within bounds for 100BASE-T Ethernet, CAN bus, and general-purpose clocking in industrial environments.

Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without an external regulator — one BOM line serves multiple core voltages.

Frequently asked questions

How do I program the DSC1101AL5-PROGT?

The DSC1101AL5-PROGT is a blank (unprogrammed) MEMS oscillator. Microchip provides a programming tool and software (typically the TimeFlash or similar programmer) that writes the desired output frequency into the device's non-volatile memory. The part is programmed on the board after assembly, or pre-programmed in a socket before placement. Consult the DSC1101 programming guide for the specific tool and procedure.

What is the output type and does it have a standby mode?

Output is CMOS (single-ended, rail-to-rail swing). Yes, the device includes a Standby (Power Down) function that disables the output and reduces current consumption to near-zero when the enable pin is pulled low.
