Product details

125 MHz LVDS clock source with AEC-Q100 grade

AEC-Q100 qualification and supply voltage range

It is suited for engine-control modules, ADAS sensor interfaces, and body-domain controllers that must survive under-hood thermal profiles. The supply range of 2.25 V to 3.63 V covers 2.5 V and 3.3 V rails without an external regulator, simplifying the power tree.

Housed in a 7.00 mm x 5.00 mm 6-SMD package with no lead exposed pad, the footprint matches industry-standard 7050 XO pinouts. The LVDS output requires a 100-Ω termination resistor across the differential pair at the receiver — the trace pair should be length-matched and impedance-controlled to preserve the 125 MHz edge integrity.

Frequently asked questions

Is DSC1123AI1-125.0000 AEC-Q100 qualified?

Yes, it is rated AEC-Q100, covering the automotive-grade temperature and reliability stress tests. This qualification makes it suitable for under-hood and cabin electronics that must meet PPAP requirements.

What is the output type of DSC1123AI1-125.0000?

The output is LVDS — a differential, low-voltage signal with a typical 350 mV swing. It is designed to drive 100-Ω terminated differential traces at 125 MHz.
