125 MHz MEMS oscillator with AEC-Q100 qualification
The DSC1001BC1-125.0000 is a 125 MHz XO (Standard) oscillator built on a MEMS resonator, delivering a CMOS output from a single supply rail spanning 1.8 V to 3.3 V. The AEC-Q100 rating means this part has passed automotive-grade reliability stress — temperature cycling, ESD, latch-up — making it suitable for cabin or chassis-domain electronics where a quartz crystal's shock sensitivity or startup jitter could be a concern.
Standby power-down and disable current
A dedicated Standby (Power Down) function drops the supply current to 15 µA max when the enable pin is de-asserted. The active-mode draw is 8.7 mA max at 125 MHz. For a module that spends most of its time asleep — an automotive TPMS sensor or a battery-backed telematics unit — the standby current is low enough that the oscillator is not the dominant drain.
Package, footprint, and temperature grade
Housed in a 4-SMD, No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm. For under-hood or extended industrial use, the DSC1001 family includes wider-temperature grades; confirm the suffix before committing the BOM.
Sourced through independent distribution; quoted to order against the BOM quantity. No pin-compatible second source is listed, but the DSC1001 series covers the same footprint with different stability and temperature options — a same-series cross is the cleanest backup plan.
