This might be a basic question but I didn't find anything on the forum about it.
I need a circuit to detect if a DAC is receiving a clock. This particular DAC needs to be put in power down state if there's no incoming master clock. Which would happen anytime the usb receiver is disconnected.
Would the attached circuit be ok ? It would be connected in between the mclk input and the pdn pin (the DAC goes to sleep when that pin is low).
