DESCRIPTION
Normal operational mode for device. If LP is left floating, then a weak internal pullup to VCC
pulls it to VCC.
Device is forced into a low-power state, causing the inputs and outputs to go to a
high-impedance state. All other inputs are ignored.
Port 1
Port 1 is selected as the active port; all other ports are low.
Port 2
Port 2 is selected as the active port; all other ports are low.
Disallowed Disallowed (Indeterminate state; all terminations are disconnected.)
HPD[1:2] follow
HPD_SINK
Standby mode: HPD[1:2] follow HPD_sink.
I2C
Device is configured by I2C logic.
GPIO
Device is configured by GPIO. If the I2C_SEL pin is left floating, then a weak internal pullup to
VCC pulls the I2C_SEL pin high.
Compliant
voltage
Driver output voltage swing precision control to aid with system compliance. The VSadj
resistor value can be selected to be 4.02 kΩ ±10% based on the system requirement to pass
HDMI compliance.

See Dissipation Ratings table
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values, except differential voltages, are with respect to network ground terminal.
