Product details

Active MEMS oscillator with automotive-grade reliability

The DSC8122BI5: The MEMS resonator eliminates quartz crystal startup jitter and vibration sensitivity, making it a fit for engine control units or ADAS sensor modules where mechanical shock is a concern.

Programming requirement and frequency flexibility

Blank (User Must Program) — this part ships unprogrammed; the target frequency between 10 MHz and 460 MHz must be written before pick-and-place, typically via Microchip's field-programmable oscillator programmer or factory-programmed service. One BOM line covers multiple frequency variants — stock a single DSC8122BI5 and program per build, reducing inventory line items for designs that need 25 MHz, 100 MHz, and 125 MHz clocks.

Frequently asked questions

What is the output type of the DSC8122BI5?

LVPECL (Low-Voltage Positive Emitter-Coupled Logic) — a differential output requiring 50-ohm termination to VCC - 2V for proper signal swing. Compatible with standard LVPECL clock receivers on FPGAs and SERDES devices.

Can the DSC8122BI5 replace the DSC8122DI2 without a PCB change?

The land patterns are incompatible, so a board spin is required. Both are same-series MEMS oscillators with LVPECL output and AEC-Q100 rating.
