Product details

The DSC1123AI5-155.5200 is a MEMS-based XO (Standard) oscillator delivering a 155.52 MHz LVDS output — a common reference frequency for 10 Gigabit Ethernet, PCIe Gen 3, and SerDes transceivers in automotive gateways and industrial controllers. Rated over -40 to 85°C with ±10 ppm frequency stability, it holds the timing budget across the full industrial temperature band without an external TCXO or oven.

Listed as Active — no NRND or EOL flags.

Frequently asked questions

Is the DSC1123AI5-155.5200 AEC-Q100 qualified?

Yes — the ratings field lists AEC-Q100. This means the oscillator has passed automotive-grade reliability testing (temperature cycling, ESD, latch-up) and is acceptable for PPAP submissions in automotive ECUs.

Does the DSC1123AI5-155.5200 have an enable/disable function?

Yes — the function is listed as Enable/Disable. When disabled, the supply current drops from 32 mA max to 22 mA max, allowing the oscillator to be gated off during system sleep states.
