MEMS resonator vs quartz — the AEC-Q100 differentiator
The DSC8001DI2T: The blank programmable type means the device ships without a pre-programmed frequency; the user must program the desired output frequency using Microchip's programming tools before assembly. This suits high-mix production where a single BOM line covers multiple frequency variants, but adds a programming step that quartz fixed-frequency oscillators skip.
Supply voltage, stability, and standby power-down
Maximum supply current is 12.2 mA during active operation.
Package and board integration
The four-pin layout (VDD, GND, output, enable/standby) matches the industry-standard pinout for this form factor, so a single PCB land pattern serves multiple suppliers. Surface-mount assembly with tape-and-reel packaging (TR) supports automated pick-and-place.
Microchip lists the DSC8001DI2T as Active (current production). The base product number DSC8001 covers the entire programmable family. For a fixed-frequency requirement, the pre-programmed variants (DSC8001xx) may be a faster path — but the blank-programmable DI2T gives the buyer control over frequency selection without stocking multiple order codes.
