The CMOS output sinks and sources up to 35 mA max — enough to drive a single clock load or a small fan-out tree on a short PCB trace. ## Enable/Disable function and power savings The Enable/Disable function (pin 1) lets the system shut down the oscillator output while keeping the MEMS resonator biased. When disabled, supply current drops to 22 mA max — useful for power-sensitive designs that need to gate the clock without a full power cycle. ## Package and board layout Housed in a 6-VDFN exposed-pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. ## Active production status No last-time-buy or end-of-life notice has been issued. Sourced through independent distribution; availability and lead time confirmed at RFQ.","metaTitle":"DSC1121AI5-041.5000 MEMS Oscillator 41.5 MHz CMOS ±10 ppm","metaDescription":"DSC1121AI5-041.5000 XO (Standard) from Microchip Technology. 41.5 MHz CMOS output, ±10 ppm stability, -40°C to +85°C.

The MEMS resonator eliminates quartz start-up delay and frequency aging, but the output logic (CMOS) and supply range (2.25V–3.6V) match typical quartz XO specifications.
