Product details

Automotive-qualified MEMS oscillator for 19.2 MHz clock trees

The DSC1001CI1-019.2000 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a 19.2 MHz CMOS output with ±50 ppm frequency stability.

Drop-in replacement for quartz — what changes

Compared to a standard 19.2 MHz quartz oscillator, the DSC1001CI1-019.2000 matches the same 4-SMD no-lead footprint and 1.8V–3.3V supply range, so it is a pin-compatible swap on existing PCB layouts. The key difference is the MEMS die inside: it eliminates quartz's frequency drift from mechanical shock and offers a faster start-up time, though the datasheet's ±50 ppm stability is comparable to a good quartz part. For a BOM line currently using a generic 19.2 MHz CMOS oscillator, this part upgrades the vibration and temperature performance without a board spin.

Frequently asked questions

Is the DSC1001CI1-019.2000 a direct replacement for a standard 19.2 MHz quartz oscillator?

Yes, it is a drop-in replacement in terms of footprint (4-SMD no-lead), supply voltage (1.8V–3.3V), and CMOS output. The MEMS resonator inside gives better shock and vibration immunity than quartz, and the AEC-Q100 qualification adds automotive-grade reliability that a generic quartz oscillator typically lacks.

What is the frequency stability of the DSC1001CI1-019.2000?

This is sufficient for most automotive and industrial serial communication clocks (CAN, LIN, UART) and general-purpose microcontroller timing.

Is the DSC1001CI1-019.2000 AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, which qualifies the part for automotive applications including under-hood and cabin electronics. The qualification covers temperature cycling, ESD, and reliability stress tests per the AEC-Q100 standard.
