Product details

135 MHz LVDS clock for automotive timing

This is a 135 MHz LVDS oscillator built on a MEMS resonator — no quartz crystal inside, so it survives the shock and vibration profile of an under-hood or chassis-mounted ECU better than a traditional XO.

AEC-Q100 qualification and rework considerations

Rated AEC-Q100, which means it passed the automotive-grade stress tests: temperature cycling, ESD, and latch-up. The 6-SMD, no-lead exposed-pad package has a large thermal pad underneath — the board needs a via array to the ground plane to pull heat out of the MEMS die during reflow. Will it survive the hot air? The exposed pad wicks heat fast — preheat the board to 100°C before hitting the part with hot air, or the pad reflows before the leads wet and you lift the part, not the pad.

Frequently asked questions

What is the frequency of DSC1123AI5-135.0000T?

The DSC1123AI5-135.0000T outputs a 135 MHz LVDS clock signal with ±10 ppm frequency stability.

Is DSC1123AI5-135.0000T AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, making it suitable for automotive applications such as ADAS cameras, radar modules, and in-vehicle Ethernet PHY reference clocks.

What is the closest pin-compatible alternative to DSC1123AI5-135.0000T?

The DSC1122 series is the same MEMS XO family with a different output type (HCSL vs LVDS). The DSC1123AI5-135.0000T uses LVDS output; if your design needs HCSL, the DSC1122 equivalent is the functional alternative, but the pinout and package are identical.
