2
I S Word Select Output.
DSD Serial Right Ch0 Data Output.
2
I S Serial Data Output / DSD Audio Output.
Configurable to be shared with DSD.
SD0 = DSD Serial Left Ch0 Data Output.
SD1 = DSD Serial Right Ch1 Data Output.
SD2 = DSD Serial Left Ch1 Data Output.
SD3 = DSD Serial Right Ch2 Data Output.
S/PDIF Audio Output. Configurable to be shared with DSD.
DSD Serial Left Ch2 Data Output.
Mute Audio Output. Signal to the external downstream audio device,
audio DAC, etc. to mute audio output.
Description
Interrupt Output. Configurable polarity and pushpull output. Multiple sources of interrupt can be
enabled through the INT_EN register.
Reset Pin. Active LOW. 5V Tolerant
2
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
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
DDC I C Clock for Port 1. 5V Tolerant. 5V Tolerant. HDCP KSV, An and Ri values are
2
exchanged over an I C port during authentication. True open drain, so does not pull to GND if
R1PWR5V is not applied.
2
DDC I C Data for Port 1. 5V Tolerant. 5V Tolerant. HDCP KSV, An and Ri values are
2
exchanged over an I C port during authentication.
True open drain, so does not pull to GND if R1PWR5V is not applied.
2
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.
2
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
Local I C 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.
Port 1 Transmitter Detect. 5V Tolerant. Used for MUTEIN function.
Reserved, must be left unconnected
Reserved, must be tied to ground
