Product details

Dual-frequency clock in a single 6-VDFN package

The DSC2311KL2-R0048 is a MEMS-based XO (Standard) that outputs two independent CMOS clock frequencies — 24 MHz on output 1 and 72 MHz on output 2 — from a single 6-VDFN package measuring 2.50 mm x 2.00 mm. This eliminates a second oscillator can and its associated PCB footprint, reducing BOM line count and layout complexity.

The 2.25 V to 3.6 V supply range lets it run directly from a 2.5 V or 3.3 V rail without an intermediate regulator.

Enable/disable for power gating

This is useful in battery-powered or duty-cycled systems where the clock can be gated during sleep modes.

Frequently asked questions

Does the DSC2311KL2-R0048 have an enable/disable function?

Yes, the function is listed as Enable/Disable. Pulling the enable pin low tri-states the outputs and reduces supply current to a maximum of 23 mA in the disabled state.

Is the DSC2311KL2-R0048 a direct replacement for a crystal oscillator?

It is a drop-in replacement in terms of function — it provides a clock output without needing external load capacitors or a feedback resistor. However, the 6-VDFN package is a surface-mount footprint different from a through-hole crystal can. Verify the PCB land pattern matches the 2.50 mm x 2.00 mm, 6-pin DFN before substituting.
