Dir Description
Output Interrupt Output. Configurable polarity and pushpull output. Multiple sources of interrupt can be
enabled through the INT_EN register.
Input Reset Pin. Active LOW. 5V Tolerant
2
Input DDC I C Clock for Port 0. 5V Tolerant. HDCP KSV, An and Ri values are exchanged over an
2
I C port during authentication. True open drain, so does not pull to GND if R0PWR5V is not applied.
2
Bi-Di DDC I C Data for Port 0. 5V Tolerant. HDCP KSV, An and Ri values are exchanged over an
2
I C during authentication. True open drain, so does not pull to GND if R0PWR5V is not applied.
2
Input DDC I C Clock for Port 1. 5V Tolerant. 5V Tolerant. HDCP KSV, An and Ri values are
exchanged over an I C port during authentication. True open drain, so does not pull to GND if
R1PWR5V is not applied.
2
Bi-Di DDC I C Data for Port 1. 5V Tolerant. 5V Tolerant. HDCP KSV, An and Ri values are
exchanged over an I C port during authentication.
True open drain, so does not pull to GND if R1PWR5V is not applied.
Input Configuration/Status I C Clock. 5V Tolerant. Chip configuration/status, CEA-861 support and
downstream HDCP repeater-specific registers are accessed via this I C port. True open drain, so
does not pull to GND if power is not applied.
Bi-Di Configuration/Status I C Data. 5V Tolerant. Chip configuration/status, CEA-861 support and
downstream HDCP repeater-specific registers are accessed via this I C port. True open drain, so
does not pull to GND if power is not applied.
2
Input Local I C Address Select. 5V Tolerant. Low = Addresses 0x60/0x68 High = Addresses 0x62/0x6A
Output Indicates Active Video at HDMI Input Port. Sync detection indicator.
Input Port 0 Transmitter Detect. 5V Tolerant. Used for MUTEIN function.
x Input ao Port 1 Transmitter Detect. 5V Tolerant. Used for MUTEIN function. u163
