Interrupt Output. Configurable polarity and pushpull
output. Multiple sources of interrupt can be
enabled through the INT_EN register.
See Note 1.
Reset Pin. Active LOW. 5V Tolerant
DDC I2C Clock for Port 0. 5V Tolerant. HDCP
KSV, An and Ri values are exchanged over an
I2C port during authentication. True open drain,
so does not pull to GND if R0PWR5V is not
applied.
DDC I2C Data for Port 0. 5V Tolerant. HDCP
KSV, An and Ri values are exchanged over an
I2C during authentication. True open drain, so
does not pull to GND if R0PWR5V is not applied.
DDC I2C Clock for Port 1. 5V Tolerant. 5V
Tolerant. HDCP KSV, An and Ri values are
exchanged over an I2C port during authentication.
True open drain, so does not pull to GND if
R1PWR5V is not applied.
DDC I2C Data for Port 1. 5V Tolerant. 5V
Tolerant. HDCP KSV, An and Ri values are
exchanged over an I2C port during authentication.
True open drain, so does not pull to GND if
R1PWR5V is not applied.
Configuration/Status I2C Clock. 5V Tolerant. Chip
configuration/status, CEA-861 support and
downstream HDCP repeater-specific registers are
accessed via this I2C port. True open drain, so
does not pull to GND if power is not applied.
Configuration/Status I2C Data. 5V Tolerant. Chip
configuration/status, CEA-861 support and
downstream HDCP repeater-specific registers are
accessed via this I2C port. True open drain, so
does not pull to GND if power is not applied.
Local I2C Address Select. 5V Tolerant. Low =
Addresses 0x60/0x68
High = Addresses 0x62/0x6A
Indicates Active Video at HDMI Input Port. Sync
detection indicator.
Port 0 Transmitter Detect. 5V Tolerant. Used for
MUTEIN function. See Note 2, 3.
Port 1 Transmitter Detect. 5V Tolerant. Used for
MUTEIN function. See Note 2,3.
