FUNCTIONAL OVERVIEW
HDMI RECEIVER
The ADV7622 front end incorporates a 4:1 multiplexed HDMI
receiver boasting support for HDMI features including 3D TV,
content type bits, and advanced features, such as capability discovery
and control. Building on the feature set of existing Analog Devices
HDMI devices, the ADV7622 also offers support for all HDTV
formats up to 36-bit, 1080p Deep Color and all display resolutions
up to UXGA (1600 × 1200 at 60 Hz).
With the inclusion of HDCP 1.4, displays can receive encrypted
video content. The HDMI interface of the ADV7622 allows for
authentication of a video receiver, decryption of encoded data
at the receiver, and renewability of that authentication during
transmission as specified by the HDCP 1.4 protocol. Repeater
support is also offered by the ADV7622.
The HDMI receiver offers advanced audio functionality. It supports
multichannel I2S audio for up to eight channels. It also supports
a 6-DSD channel interface with each channel carrying an over-
sampled 1-bit representation of the audio signal as delivered on
SACD. The ADV7622 can also receive HBR audio packet streams
and output them through the HBR interface in an S/PDIF format
conforming to the IEC 60958 standard. S/PDIF is supported via
the HPD back channel. The receiver also contains an audio mute
controller, which can detect a variety of conditions that may
result in audible extraneous noise in the audio output. On
detection of these conditions, the audio data can be ramped
to prevent audio clicks or pops.
The ADV7622 HDMI receiver incorporates active, programmable
equalization of the HDMI data signals that compensates for
the high frequency losses inherent in HDMI and DVI cabling,
especially at longer lengths and higher frequencies. The receiver
also contains a programmable data island packet interrupt
generator.
HDMI TRANSMITTER
The ADV7622 features a single HDMI transmitter supporting
ARC, 3D TV formats as well as all HDTV formats up to 1080p,
36-bit Deep Color.
Supporting both single-ended and differential modes, the ARC
feature simplifies cabling by combining an upstream audio capability
in a conventional HDMI cable.
The transmitter features an on-chip MPU with an I2C master to
perform HDCP operations and EDID reading operations.
I2C INTERFACE
The ADV7622 supports a 2-wire serial (I2C-compatible)
microprocessor bus driving multiple peripherals. The
ADV7622 is controlled by an external I2C master device,
such as a microcontroller.
OTHER FEATURES
Other features include the following:
Fully qualified software low level libraries, driver, and
application
Complete input and output audio support
Programmable interrupt request output pins: INT1, INT2,
and INT_TX
Chip select
Low power consumption: 1.8 V digital core, 1.8 V analog,
and 3.3 V digital input/output, low power power-down
mode, and green PC mode
Temperature range: 0°C to 70°C
20 mm × 20 mm, Pb-free, 144-lead LQFP
