The AMC1203
operates under one of the following conditions:
- Off state (OFF): The low-side
of the device (AVDD) is not supplied. The device is not responsive and
CLKOUT and DOUT are both low. Internally, CLKOUT and OUT are clamped to DVDD
and DGND by ESD protection diodes.
- Missing high-side supply:
DVDD is supplied but AVDD is missing. The device outputs a constant
bitstream of logic 1's or logic 0's.
- Normal operation: AVDD and
DVDD are within the recommended operating conditions. The device outputs a
digital bitstream, as explained in the Digital Output section.
