The DSC1500MA3A-PROGT is a MEMS-based XO (Standard) oscillator from Microchip's DSC150X series, delivering a clean LVCMOS clock output across a 2.3 MHz to 170 MHz frequency range. It operates from a 1.8V to 3.3V supply, so it can sit on a 1.8V FPGA bank or a 3.3V microcontroller rail without a separate regulator — one part covers multiple voltage domains in the BOM.
Package, footprint, and standby function
Housed in a 4-VFLGA package measuring 2.00mm x 1.60mm with a seated height of 0.89mm, it fits tight PCB layouts — the 0.50mm-pitch LGA pads require a fine-pitch soldering profile and a clean stencil aperture for consistent solder paste volume. A standby (power-down) pin lets the oscillator drop to near-zero quiescent current when the system sleeps, which is useful for battery-powered designs that need to conserve every microamp between wake cycles.
