Product details

125 MHz MEMS clock for automotive and industrial boards

AEC-Q100 qualification means this oscillator meets the automotive reliability stress tests — temperature cycling, ESD, and extended life — making it suitable for under-hood or chassis-mounted ECUs where a quartz crystal might drift or fail under vibration.

Standby power-down and supply flexibility

A standby (power-down) function on pin 1 drops the supply current to 15 µA max while maintaining the output in high-impedance — useful for battery-backed modules that need to preserve charge during long idle periods. The 1.8V to 3.3V supply range lets this oscillator run directly from a 1.8V core rail or a 3.3V I/O rail without an intermediate LDO, reducing BOM count and board area.

Suitable for new designs and production builds. Supplied in tube in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm.

Frequently asked questions

Is DSC1001BI5-125.0000 a direct replacement for DSC1001AI5-125.0000?

The base product number DSC1001 covers both variants. The suffix 'BI5' vs 'AI5' typically indicates a different temperature grade or stability option. Confirm the 'AI5' variant's temperature range and stability in its datasheet before substituting — if they match, the pinout and footprint are identical.

What is the standby function of DSC1001BI5-125.0000?

The standby (power-down) function disables the oscillator output and reduces supply current to 15 µA max. Driving the standby pin low puts the output into high-impedance; driving it high enables normal operation. This is useful for power-gated subsystems that need to stop the clock when idle.
