Obsolete — where is it in the cycle?
Microchip lists the DSC6112CE1A-PROGRAMMABLE as obsolete. For a shortage-desk buyer, this part is past the allocation window — the only channel now is independent surplus or broker inventory. Availability is lot-specific and confirmed at RFQ; expect spot pricing that reflects the closed franchised supply.
What the AEC-Q100 rating means for fit
It is rated for the -20 to 70°C ambient range, which covers cabin and infotainment zones but not the under-hood 105°C+ band.
Programmable frequency range and power budget
This is a factory-programmable MEMS XO covering 1 MHz to 100 MHz with ±50 ppm total frequency stability — the stability includes initial tolerance, temperature drift, and aging over the rated temperature range. Active current is 3 mA typical, dropping to 12 µA in standby mode via the Standby function pin. The wide supply tolerance (1.71-3.63 V) means a single BOM line works across multiple voltage domains without a dedicated regulator.
The footprint is standard for 3.2x2.5 mm oscillators — layout reuse across the DSC61XX family is straightforward. Surface-mount assembly with no exposed pad; the four terminals are on the package underside. Standard reflow profiles for lead-free solder apply.
