Power
Digital Supply Voltage (1.8 V).
62
ALSB
Digital input
This pin is used to set the I2C address of the Rx IO and the Tx main map.
63
CS
Digital input
Chip Select Pin. This pin must be set low or left floating for the chip to process I2C messages
that are destined for the ADV7622. The ADV7622 ignores I2C messages that it receives if this
pin is high.
64
EP_SCK
Digital output
SPI Clock Interface for the EDID.

Digital output
SPI Chip Selected Interface for the EDID.
66
EP_MOSI
Digital output
SPI Master Out/Slave In for the EDID.
67
EP_MISO
Digital input
SPI Master In/Slave Out for the EDID.
68
MCLK_IN
Digital input
Audio Reference Clock. 128 × N × fS with N = 1, 2, 3, or 4. Set to 128 × sampling frequency (fS),
256 × fS, 384 × fS, or 512 × fS. It supports CMOS logic levels from 1.8 V to 3.3 V.
69
SCLK_IN
Digital input
I2S Audio Clock. It supports CMOS logic levels from 1.8 V to 3.3 V.
70
AP5_IN
Digital input
Audio Input Port 5. It supports CMOS logic levels from 1.8 V to 3.3 V.
71
AP4_IN
Digital input
Audio Input Port 4. It supports CMOS logic levels from 1.8 V to 3.3 V.
72
DGNDIO
Ground
DVDDIO Ground.
73
DVDDIO
Power
Digital I/O Supply Voltage (3.3 V).
74
AP3_IN
Digital input
Audio Input Port 3. It supports CMOS logic levels from 1.8 V to 3.3 V.
75
AP2_IN
Digital input
Audio Input Port 2. It supports CMOS logic levels from 1.8 V to 3.3 V.
76
AP1_IN
Digital input
Audio Input Port 1. It supports CMOS logic levels from 1.8 V to 3.3 V.
77
AP0_IN
Digital input
Audio Input Port 0. It supports CMOS logic levels from 1.8 V to 3.3 V.
78
SDATA
Digital I/O
I2C Port Serial Data Input/Output Pin. SDATA is the data line for the control port.
79
SCL
Digital input
I2C Port Serial Clock Input. SCL is the clock line for the control port.
80
DGND
Ground
DVDD Ground.
81
DVDD
Power
Digital Supply Voltage (1.8 V).
82
INT1
(AMUTE1)
Digital output
Interrupt Pin. This pin can be active low or active high. When status bits change, this pin is
triggered. The events that trigger an interrupt are under user control. This pin can also
output an audio mute signal.
83
INT2
(AMUTE2)
Digital output
Interrupt Pin. This pin can be active low or active high. When status bits change, this pin is
triggered. The events that trigger an interrupt are under user control. This pin can also
output an audio mute signal.
84
INT_TX
Digital output
Interrupt; Open Drain. A 2 kΩ pull-up resistor to the microcontroller I/O supply is recommended.
85
DGNDIO
Ground
DVDDIO Ground.
86
DVDDIO
Power
Digital I/O Supply Voltage (3.3 V).
87
AP0_OUT
Digital output
Audio Output Port 0.
88
AP1_OUT
Digital output
Audio Output Port 1.
89
AP2_OUT
Digital output
Audio Output Port 2.
90
AP3_OUT
Digital output
Audio Output Port 3.
91
AP4_OUT
Digital output
Audio Output Port 4.
92
DGND
Ground
Ground for DVDD.
93
DVDD
Power
Digital Supply Voltage (1.8 V).
94
AP5_OUT
Digital output
Audio Output Port 5.
95
SCLK_OUT
Digital output
Audio Serial Clock Output.
96
MCLK_OUT
Digital output
Audio Master Clock Output.
97
RESET
Digital input
System Reset Input. Active low. A minimum low reset pulse width of 5 ms is required to
reset the ADV7622 circuitry.
98
PWRDN
Digital input
Active Low Power-Down Pin. If used, this pin should be pulled high to power up the ADV7622.
This pin can also be used as an in-system power detect where internal EDID can be powered
from a 5 V signal of the HDMI port when it is connected to active equipment.
