6.1.4 Enable/disable truth table
[1] A HIGH level on input OE_N disables only the TMDS channels.
[2] A LOW level on input DDC_EN disables only the DDC channel.
[3] OUT_Dx channels ‘enabled’ means outputs OUT_Dx toggling in accordance with IN_Dx differential input voltage switching.
[4] DDC channel ‘enabled’ means SDA_SINK is connected to SDA_SOURCE and SCL_SINK is connected to SCL_SOURCE.
[5] The HPD_SOURCE_N output logic state always follows the inverse of the HPD_SINK input logic state.

PTN3360A
Enhanced HDMI/DVI level shifter with inverting 1.1 V HPD
6.2 Analog current reference
The REXT pin (pin 6) is an analog current sense port used to provide an accurate current
reference for the differential outputs OUT_Dx. For best output voltage swing accuracy, use
of a 10 k resistor (1 % tolerance) connected between this terminal and GND is
recommended.
If an external 10 kΩ±1 % resistor is not used, this pin can be left open-circuit, or
connected to GND or V
DD
, either directly (0 ) or using pull-up or pull-down resistors of
value less than 10 k. In any of these cases, the output will function normally but at
reduced accuracy over voltage and temperature of the following parameters: output levels
(V
OL
), differential output voltage swing, and rise and fall time accuracy.
6.3 Backdrive current protection
The PTN3360A is designed for backdrive prevention on all sink-side TMDS outputs,
sink-side DDC I/Os and the HPD_SINK input. This supports user scenarios where the
display is connected and powered, but the PTN3360A is unpowered. In these cases, the
PTN3360A will sink no more than a negligible amount of leakage current, and will block
the display (sink) termination network from driving the power supply of the PTN3360A or
that of the inactive DVI or HDMI source.

[1] Input signals to these pins must be AC-coupled.
[2] Operation without external reference resistor is possible but will result in reduced output voltage swing
accuracy. For details, see Section 6.2.
