65 MHz MEMS oscillator with AEC-Q100 qualification
The DSC1121NI1-065.0000 is a 65 MHz MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a CMOS output from a 2.25V to 3.6V supply rail. Its AEC-Q100 rating means it has passed the automotive-grade reliability stress tests — temperature cycling, ESD, and latch-up — making it suitable for under-hood and cabin electronics where a quartz crystal might crack under vibration.
The wide 2.25V–3.6V supply means it can run directly off a 2.5V or 3.3V rail without an extra LDO, simplifying the power tree on a mixed-voltage board.
Active production — design-in ready
Listed as Active by Microchip, the DSC1121NI1-065.0000 is available for new designs. No end-of-life notice or successor has been issued — this is a current-production part, not a last-time-buy candidate.
6-SMD no-lead package — layout notes
Housed in a 7.00 mm x 5.00 mm 6-SMD no-lead package (0.90 mm seated height), the DSC1121NI1-065.0000 uses a standard oscillator footprint. The enable/disable function on pin 1 lets a GPIO or power supervisor gate the clock without an external buffer — useful for power-cycled subsystems in automotive ECUs.
