Product details

The DSC1001BI1-019.6608 is a MEMS-based XO (Standard) delivering a 19.6608 MHz CMOS output with ±50 ppm frequency stability across -40°C to 85°C.

Operating from 1.8V to 3.3V, a single DSC1001BI1-019.6608 can be placed on a 1.8V core rail, a 2.5V I/O rail, or a 3.3V peripheral bus without a dedicated LDO — the wide range absorbs normal rail tolerance. In an automotive body controller that sleeps between CAN wake-ups, this saves tens of milliamps compared to a non-stanby oscillator.

The package is 4-SMD, No Lead, measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. Surface-mount assembly with the no-lead package means the solder joints are under the body; confirm the PCB land pattern matches the recommended layout in the DSC1001 datasheet to avoid tombstoning or insufficient fillet height.

This is a current-design-in part, not a last-time-buy or NRND item.

Frequently asked questions

Is DSC1001BI1-019.6608 AEC-Q100 qualified?

Yes, the DSC1001BI1-019.6608 carries an AEC-Q100 rating, meaning it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up. It is suitable for under-hood and chassis-domain applications.

Does DSC1001BI1-019.6608 support a standby power-down mode?

Yes, the function is listed as Standby (Power Down). Pulling the enable pin low shuts down the output and reduces supply current to near-zero, saving power in sleep states.
