Product details

MEMS oscillator for tight-timing boards

The DSC1121BI5-024.5760T is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a fixed 24.576 MHz CMOS output with an absolute pull range of ±10 ppm.

Industrial temperature and enable/disable control

The Enable/Disable function (pin-controlled) lets the system shut down the clock tree when idle; max supply current is 35 mA running and 22 mA when disabled, which helps meet standby power budgets in always-on equipment.

It is suitable for both new designs and ongoing production builds. Supplied in Tape & Reel (TR) packaging, consistent with automated pick-and-place assembly.

Frequently asked questions

How does the Enable/Disable function work on this oscillator?

The Enable/Disable pin (pin 1 on the 6-VDFN) gates the CMOS output. When disabled, the output goes high-impedance and supply current drops from 35 mA max to 22 mA max — useful for power gating in battery-operated or duty-cycled systems.

Is the DSC1121BI5-024.5760T a direct replacement for a quartz oscillator at 24.576 MHz?

It is a MEMS-based XO, not a quartz crystal — it includes the resonator and oscillator on-chip. The CMOS output and 2.25V–3.6V supply make it a drop-in for many 24.576 MHz clock inputs on Ethernet PHYs, audio codecs, or FPGA reference clocks, but confirm the footprint (6-VDFN, 5.00mm x 3.20mm) matches your PCB land pattern.
