The DSC1001DE1-120.0000 is a 120 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a CMOS output with ±50ppm frequency stability across its -20°C to 70°C operating range.
Supply voltage flexibility and board-level fit
The 1.8V to 3.3V supply range covers the three most common digital I/O rails — a single BOM line can serve a 1.8V FPGA bank, a 2.5V SoC, or a 3.3V microcontroller without a separate voltage translator. Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the footprint is compatible with standard MEMS oscillator land patterns — no special via-in-pad or thermal relief required. Maximum supply current is 8.7 mA at 120 MHz — the MEMS resonator draws less than a comparable quartz fundamental-mode crystal, which helps keep the local thermal rise low in dense layouts.
