Product details

Automotive-grade MEMS oscillator at 66 MHz

The supply voltage range spans 1.8V to 3.3V, so the same oscillator can serve a 1.8V FPGA core clock, a 2.5V SerDes reference, or a 3.3V microcontroller — one BOM line covers multiple voltage domains. Maximum supply current is 7.2 mA, which is typical for a 66 MHz CMOS oscillator at 3.3V. For a CAN transceiver or sensor node that sleeps between bus cycles, that 15 µA standby draw avoids draining the battery during extended idle periods.

Active lifecycle — no EOL risk for new designs

No last-time-buy window or successor part number has been announced. Procurement can commit this to a BOM without planning for an obsolescence migration. The no-lead package measures 5.00 mm × 3.20 mm with a seated height of 0.90 mm.

Frequently asked questions

Is the DSC1001BI2-066.0000T AEC-Q100 qualified?

Yes. The DSC1001BI2-066.0000T is rated AEC-Q100, meaning it has passed the automotive-grade qualification tests for temperature, reliability, and ESD. It is suitable for use in automotive electronic modules without additional qualification paperwork.

Can the DSC1001BI2-066.0000T replace a quartz oscillator of the same frequency?

The MEMS resonator offers better shock and vibration tolerance than quartz, which is an advantage in automotive and industrial environments. The standby power-down function (15 µA max disable current) may also save power compared to a quartz oscillator that lacks a disable pin.
