EXTCLK
The electrical characteristics of the EXTCLK input are shown in Table 20. The EXTCLK
input supports an AC-coupled sine-wave input clock or a DC-coupled square-wave
input clock.
If EXTCLK is AC-coupled to the AR0833 and the clock is stopped, the EXTCLK input to
the AR0833 must be driven to ground or to VDD_IO. Failure to do this will result in exces-
sive current consumption within the EXTCLK input receiver.
