Product details

MEMS oscillator at 125 MHz — no quartz, no tuning

Output is standard CMOS, so it drives FPGA clock inputs, SoC reference pins, and logic buffers directly at 3.3V without a level translator.

Power budget and standby control

The standby pin lets a host MCU or power-management IC gate the clock tree, keeping the oscillator off until the system needs to wake.

Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits dense PCB layouts without consuming routing channels.

No stock-holding claim — availability confirmed at RFQ.

Frequently asked questions

Is the DSC1033DI1-125.0000T compatible with 3.3V FPGA clock inputs?

Yes. The output is standard CMOS at 3.3V supply, so it drives FPGA clock inputs, SoC reference pins, and 3.3V logic directly without external translation.

What is the closest alternative to the DSC1033DI1-125.0000T if it is unavailable?

No pin-compatible second source is listed on the evidence. Within the same Microchip DSC1033 family, other frequency variants share the same package and supply voltage — confirm the exact frequency and stability grade before substituting.
