No second LDO needed when the board has both voltage domains; the oscillator runs from whichever rail is cleaner. The disable current max is 22 mA, compared to 35 mA max when running — useful for battery-powered gear that sleeps between transmissions. Housed in a 6-VDFN with exposed pad, 7.00 mm x 5.00 mm footprint, seated height 0.90 mm max. Surface-mount on tape and reel — the 0.90 mm height fits under a mezzanine board or inside a compact enclosure without a clearance spacer. Product status is Active per Microchip.","metaTitle":"DSC1121AM2-041.5000T MEMS XO 41.5 MHz CMOS -55 to 125°C","metaDescription":"Microchip DSC1121AM2-041.5000T XO (Standard), 41.5 MHz CMOS output, ±25ppm stability, 2.25-3.6V supply, -55 to +125°C.

The DSC1121AM2-041.5000T is a MEMS XO with CMOS output and the same 2.5V–3.3V supply range as most quartz oscillators. However, the 6-VDFN package footprint (7.00 mm x 5.00 mm) differs from common 5.0 mm x 3.2 mm or 7.0 mm x 5.0 mm quartz packages — confirm the pad layout on your board before substituting."},{"question":"What supply voltage does the DSC1121AM2-041.5000T accept?","answer":"It accepts 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails.
