What this MEMS oscillator covers and where it fits
The DSC1101CL5-PROGT is a MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a CMOS output across 2.3 MHz to 170 MHz — a span that covers common MCU clocks, Ethernet PHY references, and FPGA configuration oscillators in one part number. It ships as a blank device (Programmable Type: Blank (User Must Program)), so you program the exact frequency at your line — no need to stock multiple fixed-frequency SKUs.
Housed in a 6-VDFN measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the 0.50 mm pitch pads are exposed on the bottom, so the reflow profile needs a good soak above solder liquidus to wet the centre pad. Standby (Power Down) function lets you pull the output to high-Z and drop current to near-zero — handy for power-gated sections where the oscillator must not keep running when the domain is off.
