Product details

MEMS XO with 2.3 MHz to 170 MHz programmability

The DSC1500AA3A-PROG is a MEMS-based XO (Standard) from Microchip's DSC150X series, offering a programmable frequency range from 2.3 MHz to 170 MHz. It outputs LVCMOS and operates across a wide supply voltage range of 1.8V to 3.3V, making it a single-BOM fit for multi-rail designs where the same oscillator must work across 1.8V, 2.5V, and 3.3V logic domains. The 7.5mA max supply current keeps the thermal budget light in dense boards.

Standby function and package footprint

Housed in a 4-VDFN with exposed pad measuring 7.00mm x 5.00mm x 0.90mm seated height, the package is suited for surface-mount assembly.

Active lifecycle — sourcing through independent distribution

Microchip lists the DSC1500AA3A-PROG as Active.

Frequently asked questions

What is the function of the standby pin on the DSC1500AA3A-PROG?

The Standby (Power Down) pin shuts down the oscillator output and internal circuitry, reducing current consumption to near zero. This is useful for gating the clock in low-power or intermittent-duty systems without an external load switch.

Is the DSC1500AA3A-PROG a direct replacement for the DSC1500AA3A?

The evidence does not contain a direct comparison between DSC1500AA3A-PROG and DSC1500AA3A. Confirm pinout, programming, and electrical compatibility from the respective datasheets before substituting.
