Obsolete — last-time-buy sourcing
The DSC6111ME2A-PROGRAMMABLE: Microchip has marked this part obsolete. No pin-compatible direct replacement from Microchip is documented.
MEMS oscillator core and output
Programmable across 1 MHz to 100 MHz via Microchip's factory programming — one order code covers the full range, so a single BOM line can serve multiple frequency requirements if the design accepts a single frequency per unit.
Automotive-grade timing
AEC-Q100 qualified — this is automotive IC stress qualification covering temperature cycling, ESD, and reliability screening. For a 100 MHz reference, ±25 ppm is ±2.5 kHz of absolute error, tight enough for most CAN, LIN, and general-purpose MCU clock trees.
Power budget and standby
Active current draw is 3 mA typ at full supply range — negligible in a system burning hundreds of milliamps. The standby function drops consumption to 12 µA max with the output disabled, preserving battery in sleep-mode applications. The wide range simplifies power sequencing: the oscillator starts before the core supply stabilizes.
Package and board-fit
The 2.0 mm x 1.6 mm footprint matches industry-standard 2016-size crystal oscillator pads — drop-in compatible with quartz XO footprints of the same dimensions. For automotive under-hood use requiring -40°C to +125°C, this part's temperature window is insufficient; the AEC-Q100 rating here covers the lower-temperature cabin-grade qualification, not the full automotive temperature span.
