Product details

The DSC1101CI5-125.0000T: Its supply voltage spans 2.25V to 3.6V, so it runs directly off a 2.5V or 3.3V rail without an extra LDO — a clean fit for FPGAs, Ethernet PHYs, or high-speed MCUs that need a precise 125 MHz reference.

Supply current and standby power-down

At 125 MHz the oscillator draws 35 mA maximum — that is the peak into a CMOS load, so budget this into the power rail for a multi-oscillator design.

Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, this oscillator fits tight board layouts.

Frequently asked questions

Can the DSC1101CI5-125.0000T replace a standard quartz oscillator?

Functionally yes — it is a drop-in 125 MHz CMOS oscillator with tighter ±10 ppm stability than many quartz XOs. The MEMS resonator is more shock-tolerant, but the pinout and footprint (6-SMD no-lead) are standard. Verify the supply voltage and enable logic match your board.
