Maximum supply current is specified at 3 mA typ — low enough that a 1.8 V rail with 10 mA headroom can feed the oscillator and still leave margin for the load capacitance and termination. ## Temperature stability and deployment envelope The CMOS output swing is rail-to-rail, so the oscillator drives standard digital inputs directly; no external bias or termination network is required for short PCB traces under 50 mm.","metaTitle":"DSC6121HI2A-00AK MEMS XO, 25/27MHz, 1.71-3.63V, CMOS","metaDescription":"Microchip DSC6121HI2A-00AK MEMS XO, dual CMOS outputs 25MHz & 27MHz, ±25ppm stability, 3mA typ.
