AEC-Q100 MEMS XO, now obsolete
The DSC6001HI1A-PROGRAMMABLE is an AEC-Q100-qualified MEMS-based XO (Standard) oscillator from Microchip's DSC60XX series, producing a CMOS output across a programmable frequency range of 1 MHz to 80 MHz. Its supply operates from 1.71V to 3.63V, drawing 1.3 mA typical, and it includes an Enable/Disable function. The part is now marked Obsolete by the manufacturer.
Programmable frequency, fixed footprint
The oscillator can be programmed to any frequency within its 1 MHz to 80 MHz range, not just standard values, which simplifies BOM consolidation across multiple clock requirements. The 4-SMD, no-lead package measures 1.60mm x 1.20mm with a seated height of 0.89mm, matching the common 1.6 x 1.2 mm MEMS oscillator footprint. The ±50 ppm total frequency stability covers temperature, supply, and aging effects.
Microchip has classified the DSC6001HI1A-PROGRAMMABLE as Obsolete. No official successor part number is provided in the lifecycle record. For new designs, a functionally equivalent AEC-Q100 MEMS oscillator in the same 1.6 x 1.2 mm footprint should be evaluated — the DSC60XX series may have active siblings, but no pin-compatible replacement is documented here.
