The DSC1033AC1-050.0000 is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 50 MHz CMOS output from a 3.3V supply rail.
For a battery-powered sensor node that sleeps between readings, the 1µA standby current means the oscillator's own draw is negligible against the system's sleep budget.
Yes, the output is CMOS, so it drives standard CMOS logic inputs directly without external level translation.
Yes, it includes a Standby (Power Down) function that reduces the supply current to 1µA maximum when disabled.
This is a MEMS-based XO, not a bare crystal. It integrates the resonator and oscillator circuit in one package, provides a CMOS output at 3.3V, and includes a standby feature — a quartz crystal oscillator module would need an external load cap and inverter stage.
