Product details

745 kHz fixed-frequency MEMS XO for automotive timing

The 1.8V to 3.3V supply range lets it run directly off a 1.8V core rail or a 3.3V I/O rail without a separate LDO — useful when the same BOM position serves multiple voltage domains.

AEC-Q100 qualification and active production status

AEC-Q100 qualified (Grade 2 by temperature range), the part meets the stress, reliability, and PPAP requirements for automotive electronics — suitable for cabin or under-hood modules that see -40°C cold starts and 85°C continuous soak.

4-VFLGA package and enable/disable function

Housed in a 4-VFLGA package measuring 1.60 mm x 1.20 mm with a seated height of 0.89 mm, the footprint is small enough for space-constrained automotive modules or portable instruments — the 0.50 mm pitch LGA demands careful solder-paste stencil design and a clean reflow profile to avoid bridging.

Frequently asked questions

What is the frequency of DSC6003HI2B-745K000?

The DSC6003HI2B-745K000 outputs a fixed 745 kHz CMOS clock. That frequency is non-standard — it is not a common multiple of 32.768 kHz or a standard CAN/LIN bus clock — so confirm your target peripheral or MCU timer can accept 745 kHz before committing the BOM line.

Is DSC6003HI2B-745K000 AEC-Q100 qualified for automotive?

Yes, it carries AEC-Q100 qualification. Combined with the -40°C to 85°C operating range, it meets the reliability and temperature requirements for automotive cabin and under-hood applications.

Does DSC6003HI2B-745K000 have an enable/disable function?

Yes, the Enable/Disable function allows the output to be tri-stated or shut down under logic control. This is useful for power gating the clock during sleep modes in battery-powered or automotive systems.
