The DSC1001AE5-004.0000 is a 4 MHz MEMS-based XO (Standard) oscillator from Microchip Technology's DSC1001 series, delivering a CMOS output with ±10 ppm frequency stability across its operating range.
Supply voltage flexibility and temperature range
The supply voltage range spans 1.8V to 3.3V, so the same oscillator can serve a 1.8V MCU core clock, a 2.5V FPGA reference, or a 3.3V peripheral bus without a separate voltage rail — one BOM line covers multiple designs.
Package, mounting, and board integration
The 4-SMD, No Lead Exposed Pad package measures 7.00mm x 5.00mm with a seated height of 0.90mm — a standard footprint that reflows with the same profile as most QFN packages on the board. Surface-mount assembly with the exposed pad provides a low-inductance ground return, which helps keep the output edge clean and reduces EMI coupling into adjacent traces.
