Product details

112.24 MHz MEMS clock for industrial timing

Its 2.25V to 3.6V supply range lets a single BOM line serve both 2.5V and 3.3V clock domains without a separate regulator or voltage translator.

Package and board layout notes

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — the exposed pad on the underside should be soldered to a ground-plane thermal land for best jitter and thermal performance. The 22 mA maximum supply current (unloaded) sets a modest power budget; the MEMS resonator draws less than a quartz crystal oscillator at the same frequency, which helps keep the local temperature rise low in a dense layout.

Frequently asked questions

Is the DSC1121AL5-112.2400 RoHS compliant?

The evidence does not list a specific RoHS compliance statement, but Microchip's standard MEMS oscillator families are generally RoHS-compliant and lead-free. Confirm with the datasheet or your Microchip FAE for the exact compliance declaration.

How do I enable or disable the output on the DSC1121AL5?

The Enable/Disable function on pin 1 tri-states the output when pulled low. This allows system-level power management or test without removing power from the oscillator.

Can the DSC1121AL5-112.2400 replace a standard 112.24 MHz quartz oscillator?

Yes — it is a drop-in MEMS replacement for a 112.24 MHz quartz XO in the same 7 mm x 5 mm footprint. The MEMS resonator offers better shock and vibration tolerance than quartz, and the ±10 ppm stability is comparable to a temperature-compensated quartz oscillator.
