Product details

Programmable MEMS oscillator for flexible timing trees

The DSC1101CL3-PROGT is a blank-programmable MEMS oscillator from Microchip's DSC1101 series — it ships unprogrammed and you set the output frequency anywhere from 2.3 MHz to 170 MHz using Microchip's programming tools or a distributor programming service. A single BOM line covers multiple frequency variants: instead of stocking a separate fixed-frequency can for every clock speed, you program the same part number to the exact frequency needed per board revision or product variant.

The supply voltage range spans 2.25 V to 3.6 V, so it runs directly off a 3.3 V or 2.5 V rail without an extra LDO — handy when you're consolidating power domains on a mixed-voltage board.

Standby function and CMOS output

A standby (power-down) pin lets you shut the oscillator off when the system sleeps — the 35 mA max supply current drops to near zero in standby, saving power in battery-operated or duty-cycled designs. CMOS output levels are compatible with most MCU, FPGA, and logic inputs without external level translation, as long as the supply voltage matches the receiving device's I/O bank.

Frequently asked questions

How do I program the DSC1101CL3-PROGT?

The part ships as a blank device (Programmable Type: Blank (User Must Program)). You program the output frequency using Microchip's TimeFlash field programmer or a compatible programming fixture. Some distributors also offer a pre-programming service — confirm at RFQ if you need programmed parts rather than blanks.

Is the DSC1101CL3-PROGT a drop-in replacement for a fixed-frequency quartz oscillator?

It can replace a fixed-frequency oscillator in the same 6-VDFN footprint (3.20 mm x 2.50 mm, 0.90 mm seated height) if the supply voltage, output type (CMOS), and frequency stability (±20 ppm total) match your existing design. The key difference: you must program the frequency before assembly, whereas a fixed-frequency can is ready out of the tube.

What is the frequency stability of the DSC1101CL3-PROGT?

This is tight enough for most MCU clocking, UART baud-rate generation, and general-purpose timing — but not for precision RF or wireless base-station references that require ±5 ppm or better.
