Product details

The supply voltage accepts 2.25V to 3.6V, so the oscillator can run directly from a 3.3V or 2.5V rail without a dedicated regulator — a single decoupling cap at the VDD pin is sufficient.

Standby power-down for battery-conscious designs

6-SMD no-lead package and board integration

Housed in a 5.00 mm x 3.20 mm 6-SMD no-lead package with a seated height of 0.90 mm max, the DSC1101BI2-125.0031 fits the standard 5x3.2 mm oscillator footprint and reflows with a typical lead-free profile — no via-in-pad or special stencil required. The surface-mount package is compatible with automated pick-and-place and reflow assembly; the no-lead construction reduces parasitic inductance compared to a gull-wing package at 125 MHz.

Frequently asked questions

How does the standby power-down function work on this oscillator?

A logic-low on the standby pin disables the CMOS output and reduces supply current to 95 µA max, allowing the clock tree to be shut down under firmware control without a separate load switch.

What is the closest pin-compatible alternative in the DSC1101 family?

Any DSC1101 variant with the same 6-SMD no-lead package and supply voltage range is pin-compatible — the difference is frequency and stability grade. For a different frequency, select the corresponding DSC1101 order code; the footprint and pinout are identical across the series.
