The DSC6001JI2A-027.0000 is a MEMS-based XO (Standard) from Microchip's DSC60XX series, outputting a 27 MHz CMOS clock. Rated for -40°C to 85°C and AEC-Q100 qualified, this oscillator is suited for automotive cabin and chassis-domain modules — the MEMS die handles the thermal cycling and mechanical stress of under-hood environments without the frequency drift a quartz resonator might show. The Enable/Disable function lets the system shut down the oscillator output for power savings — the 1.3 mA typical supply current at 27 MHz is already low, but disabling the output when the clock tree is idle cuts it further.
Microchip lists the DSC6001JI2A-027.0000 as Obsolete. If your design is still in development, consider migrating to a current-production MEMS oscillator from the DSC60XX family with the same 4-SMD no-lead footprint and 1.71V–3.63V supply range. Confirm the frequency stability and AEC-Q grade match your target before spinning the board.
The 4-SMD, No Lead package measures 2.50 mm x 2.00 mm with a seated height of 0.89 mm. Supplied in tube.
