The MEMS die is inherently more resistant to shock and vibration than a quartz blank — relevant if this board lives in a motor drive, a fan wall, or a vehicle cabin where the crystal's mechanical resonance can drift under G-force. Output is CMOS, single-ended, with an Enable/Disable function that pulls the output to high-impedance when the enable pin is de-asserted. The disable current drops to 22 mA max from the 35 mA max active draw — modest savings, but useful if the oscillator is gated during a low-power sleep mode. Supply voltage range is 2.25V to 3.6V, covering the common 2.5V, 3.0V, and 3.3V logic rails. No external LDO needed if the rail is within that window — the oscillator's internal regulator handles the MEMS drive voltage. ## Package and board-fit The 6-VDFN exposed pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm max. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1121AL5-041.5000T MEMS XO 41.5 MHz CMOS - Microchip","metaDescription":"Microchip DSC1121AL5-041.5000T MEMS oscillator, 41.5 MHz CMOS output, 2.25-3.6V supply, -40 to 105°C.
