1). Y and Z terminal ESD Diode notice.
Y and Z terminals are connected ESD diode.

BU16028KV flow leak current from AVCC to VCC.
In order to minimize leak current.
Please use following application.

2). HPD_SINK Pull down resistance.
HPD_SINK is a 5V tolerant structure shown in Fig6-2.
It needs some drive current to pull down HPD_SINK "H" to "L"(max10uA@HPD_SINK=2V).
So to pull down HPD_SINK, please use 10k
Ω
(or under 10k
Ω
) resistor.
