MEMS oscillator with automotive qualification — now obsolete
The DSC6001HE2A-022.0000T is a 22 MHz MEMS-based XO (standard oscillator) from Microchip's DSC60XX series, delivering a CMOS output with ±25ppm frequency stability across its -20°C to +70°C operating range. It carries AEC-Q100 qualification, meaning it was originally qualified for automotive-grade reliability — a signal that the part was designed for environments requiring stress screening and PPAP documentation. The supply voltage spans 1.71V to 3.63V, covering 1.8V, 2.5V, and 3.3V logic rails without an external regulator, and the Enable/Disable function lets the system gate the output for power savings.
Lifecycle reality — last-time-buy window closed
For existing BOM lines that depend on this oscillator, the only sourcing path is through independent surplus channels.
Housed in a 4-SMD, No Lead package measuring 1.60mm x 1.20mm with a seated height of 0.89mm — the 1.6 × 1.2 mm footprint is common among MEMS oscillators, but the pad layout must match the manufacturer's recommended land pattern for reliable solder-joint formation.
