MEMS oscillator at 322 MHz with LVPECL output
The DSC1122BI2-322.0000 is a MEMS-based XO (Standard) from Microchip's DSC1122 series, delivering a 322 MHz LVPECL output. The MEMS resonator replaces a quartz crystal, offering better shock and vibration immunity — relevant for industrial or mobile applications where a quartz oscillator might drift or fail under mechanical stress.
Power and enable/disable function
Maximum supply current is 58 mA when enabled; pulling the Enable/Disable pin low drops the draw to 22 mA max. This is useful for power-sensitive designs — the oscillator can be gated off during sleep modes without a separate load switch.
