SIGNAL | LEVEL(1) | STATE | DESCRIPTION |
---|---|---|---|
OE_N | H | Power Saving Mode | Main Link is disabled. IN_Dx termination = 50 Ω with common mode voltage set to 0V. OUT_Dx outputs = high impedance |
L | Normal Mode | IN_Dx termination = 50 Ω OUT_Dx outputs = active |
|
I2C_EN | H | HDMI | The Internal I2C register is active and readable when the TMDS port is selected indicating that the connector being used is HDMI. This mode selects the fastest rise and fall time for the TMDS differential output signals |
L | DVI | The Internal I2C register is disabled and not readable when the TMDS port is selected indicating that the connector being used is DVI. This mode selects a slower rise and fall time for the TMDS differential output signals See Application Information. |
|
VSadj | 4.02 kΩ ±5% | Output Voltage Swing Contol | Driver output voltage swing precision control to aid with system compliance |
HPDINV | H | HPD Inversion | HPD_SOURCE VOH =0.9V (typical) and HPD logic is inverted |
L | HPD non-inversion | HPD_SOURCE VOH =3.2V (typical) and HPD logic is non-inverted | |
SRC | H | Edge Rate: Slowest | SRC helps to slow down the rise and fall time. SRC =High adds ~60ps to the rise and fall time of the TMDS differential output signals in addition to the I2C_EN pin selection (recommended setting) |
L | Edge Rate: Slow | SRC helps to slow down the rise and fall time. SRC =Low adds ~30ps to the rise and fall time of the TMDS differential output signals in addition to the I2C_EN pin selection | |
Hi-Z | Edge Rate | Leaving the SRC pin High Z, will keep the default rise and fall time of the TMDS differential output signals as selected by the I2C_EN pin. It is recommended that an external resistor-divider (less than 100 kΩ) is used so that voltage on this pin = VCC/2, if Hi-Z logic level is intended on this pin. |
|
OVS | H | Offset 1 | DDC source side VOL and VIL offset range 1 |
L | Offset 2 | DDC source side VOL and VIL offset range 2 | |
Hi-Z | Offset 3 | DDC source side VOL and VIL offset range 3 It is recommended that an external resistor-divider (less than 100 kΩ) is used so that voltage on this pin = VCC/2, if Hi-Z logic level is intended on this pin. |
|
DDC_EN | H | DDC Buffer enabled | DDC Buffer is enabled |
L | DDC buffer disabled | DDC Buffer is disabled |
