Obsolete MEMS XO – sourcing reality for 20 MHz automotive clock
No pin-compatible successor from Microchip is cited in the lifecycle record.
Automotive-grade MEMS oscillator – what the AEC-Q100 rating means
The MEMS base resonator inherently withstands higher g-levels than a quartz crystal, making the DSC60XX family a fit for engine control units, transmission modules, and ADAS sensor hubs that see mechanical stress.
20 MHz CMOS clock – supply and timing budget
Delivers a 20 MHz CMOS output with ±25 ppm frequency stability, running from a 1.71 V to 3.63 V supply and drawing 1.3 mA typical – a low-power fixed-frequency clock for an MCU or SoC reference.
