Product details

The DSC1025BI1-125.0000 is a MEMS-based XO (Standard) oscillator delivering a 125 MHz CMOS output on a 2.5V rail — a clean, low-jitter clock for FPGAs, SoCs, or high-speed serial interfaces that need a fixed-frequency reference without a quartz crystal's startup time.

Standby power-down for battery-conscious builds

Active draw is 10 mA max at 125 MHz, so the standby savings matter most in duty-cycled applications like wireless sensor nodes or handheld instruments.

4-SMD no-lead footprint — hand-solderable with care

The 5.00 mm x 3.20 mm body with 0.90 mm seated height uses a standard 4-SMD, No Lead land pattern — fine for reflow or hot-air rework, and a steady hand with a fine-tip iron can manage it if the pads are pre-tinned.

Frequently asked questions

Is the DSC1025BI1-125.0000 obsolete?

Yes — Microchip lists this part as Obsolete. It is no longer in production and is not recommended for new designs. Existing BOM lines can be filled through independent surplus channels; quantities are confirmed per RFQ.
