Product details

148.5 MHz LVDS clock with automotive-grade qualification

Rated AEC-Q100, this oscillator is qualified for automotive applications — the MEMS die and ASIC are built to withstand the shock, vibration, and thermal cycling found in under-hood and cabin electronics. The Enable/Disable function lets the system shut down the output without cycling the supply, reducing current draw from 32 mA (max) to 22 mA (max) when the clock is not needed.

Surface-mount footprint and layout notes

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1123AI2-148.5000 fits the standard 7x5 mm oscillator footprint common in networking and video equipment.

Frequently asked questions

Can DSC1123AI2-148.5000 replace a standard quartz crystal oscillator?

Yes — the DSC1123AI2-148.5000 is a drop-in replacement for a 7x5 mm LVDS oscillator. The MEMS resonator inside is more resistant to shock and vibration than a quartz crystal, and the ±25 ppm stability matches the performance of many quartz-based XOs. No external load capacitors are needed; the output is a differential LVDS signal that drives 100-ohm terminated lines directly.

Is DSC1123AI2-148.5000 suitable for automotive applications?

Yes — it is rated AEC-Q100, the automotive IC qualification standard. The MEMS resonator also passes the AEC-Q100 mechanical shock and vibration tests, making it suitable for engine control units, ADAS cameras, and infotainment modules.
