Product details

The DSC8122CI5T: For a power-train or chassis-domain ECU that sees -40°C cold starts and 85°C under-hood soak, the grade-2 temperature range is the relevant reliability floor.

Blank-programmable — frequency set at the line

The DSC8122CI5T ships as a blank (user-programmable) device. The frequency is set during board-level programming via Microchip's TimeFlash or a production programmer. This avoids stocking multiple fixed-frequency SKUs — one BOM line covers the full 10 MHz to 460 MHz range, and the frequency is locked at the last step before reflow.

The land pattern matches the standard 6-pin MEMS oscillator footprint — no via-in-pad required. The enable/disable pin pulls the output to high-impedance when driven low, which lets multiple oscillators share a clock bus without contention.

Frequently asked questions

What is the output type of DSC8122CI5T?

The DSC8122CI5T outputs LVPECL. LVPECL is a differential signal with a typical 800 mV swing centered around a 2 V common-mode voltage — it drives 50-ohm terminated transmission lines directly without an external buffer. The differential pair must be routed as a controlled-impedance pair on the PCB.

What compliance documentation does Microchip provide for DSC8122CI5T?

Microchip provides RoHS and REACH compliance documentation for the DSC8122CI5T as part of the standard product documentation package. The part is lead-free and meets the EU RoHS directive. No UL or IEC certification is listed for this oscillator class.
