Product details

Active MEMS XO at 9.091 kHz

Supply flexibility and output drive

The device operates across a 1.8V to 3.3V supply range, allowing it to be powered from a common 1.8V, 2.5V, or 3.3V rail without an external LDO. The CMOS output swings rail-to-rail, simplifying interface with MCU or FPGA clock inputs.

Housed in a 4-VFLGA package measuring 1.6 mm x 1.2 mm with a seated height of 0.89 mm, this is a tiny land-grid array footprint. Surface-mount assembly on standard FR-4 is fine, but the small pad area means the oscillator relies on the PCB copper for thermal relief during reflow. No underfill is required for the temperature range.

Frequently asked questions

Is DSC6001HE1B-009K091T AEC-Q100 qualified?

Yes, the DSC6001HE1B-009K091T carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up. This qualifies it for use in under-hood and cabin electronics where the ambient temperature stays within -20°C to +70°C.

Can DSC6001HE1B-009K091T replace a standard quartz oscillator?

Functionally yes — it is a drop-in XO replacement with a CMOS output. However, the MEMS resonator gives it better shock and vibration tolerance than quartz, and the 1.6 mm x 1.2 mm VFLGA package is smaller than most quartz SMD cans. Verify the footprint matches your PCB land pattern before substitution.

What is the frequency stability of DSC6001HE1B-009K091T?

Frequency stability is specified at ±50 ppm across the operating temperature range. This is adequate for general-purpose timing and low-speed serial interfaces, but not for precision RF or high-speed data converters that require tighter ±20 ppm or better.
