Product details

34 MHz LVDS clock for automotive ECUs

The DSC1123BI5-034.0000: LVDS signalling keeps the edge rates clean over short PCB traces to the downstream FPGA or SoC — no extra termination resistors needed if the receiver is AC-coupled. Supply voltage spans 2.25V to 3.63V, so the same part runs on a 2.5V or 3.3V rail without a separate LDO.

AEC-Q100 Grade 1 — under-hood ready

That covers cabin electronics, ADAS sensor modules, and infotainment head units — but not the engine bay or exhaust-side sensors where ambient exceeds 85°C.

MEMS resonator vs quartz — same footprint, no trade-off

That means no crystal aging drift, no start-up reliability issues from mechanical shock, and a tighter ±10 ppm stability over temperature without an external tuning cap. The 6-SMD no-lead package is footprint-compatible with standard 5.0 mm × 3.2 mm quartz oscillators — a drop-in replacement on the same PCB land pattern.

Frequently asked questions

Is the DSC1123BI5-034.0000 AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating.

Can the DSC1123BI5-034.0000 replace a standard quartz oscillator?

Yes. The MEMS resonator eliminates crystal aging drift and improves shock resistance — no external load capacitors are needed.

What is the output type of the DSC1123BI5-034.0000?

LVDS. The differential output provides low-jitter clocking for high-speed serial interfaces. The enable/disable function allows the output to be tri-stated for power savings.
