The DSC1103AI5-120.0000T is a 120 MHz LVDS-output MEMS oscillator from Microchip's DSC1103 series. It delivers a clean differential clock for high-speed serial interfaces — think 1 GigE, SATA, or PCIe reference clocks — where single-ended CMOS would radiate or suffer common-mode noise.
Supply range and standby power-down
Supply voltage spans 2.25V to 3.63V, so it runs from a 2.5V or 3.3V rail without an extra regulator. The wide tolerance also helps during power-up sequencing when the rail may ramp slowly. Active current draw is 32 mA max at 120 MHz, typical for an LVDS oscillator at this frequency; the differential output keeps the power-per-bit lower than a CMOS oscillator driving the same trace length.
