10.4 CEC
The IP4777CZ38 includes a hot plug detect circuit that simplifies the hot plug application.
The circuit generates a standard logic level from the hot plug signal.
The hot plug detect circuit is pulling down the signal to avoid any floating signal. The
comparator guarantees a save detection of the 2 V hot plug signal without any glitches
and oscillation at the hot plug output.
The CEC signal can generate distortions caused by signal ringing in a 1 kHz domain. The
CEC slew rate limiter ensures that a signal does not ring independently of the CEC slave
that is releasing the signal.
A MOSFET transistor implements the backdrive protection which blocks signals in a
power-down state.
The slew rate of the CEC bus is controlled by a slew rate that is defined independently of
the load (resistive and capacitive) at the CEC bus.
