Product details

Frequency stability and temperature envelope

The DSC1124DE1-125.0000: Max supply current is 42 mA when active, dropping to 22 mA with the output disabled — the disable current is still non-trivial, so if you are designing a battery-powered device that sleeps most of the time, plan a load switch ahead of the oscillator supply.

Package and board integration

Surface-mount only — no through-hole variant in this series, so it is a reflow-only part. The no-lead construction keeps the parasitic inductance low, which helps maintain signal integrity on the 125 MHz HCSL edge rates.

Frequently asked questions

What is the output type and frequency of DSC1124DE1-125.0000?

The output is HCSL (High-Speed Current Steering Logic) at a fixed 125 MHz. HCSL is a differential standard commonly used for PCIe reference clocks, requiring a 50-ohm termination to ground on each output leg.

What supply voltage does DSC1124DE1-125.0000 need?

No external regulator is needed if your board already has one of these rails.

Is there a pin-compatible alternative to DSC1124DE1-125.0000?

The DSC1124 series shares the same footprint and pinout across frequencies, so a different frequency in the same series would fit the same PCB layout, but the output type and supply range must match.
