FUNCTIONAL OVERVIEW
HDMI RECEIVER
The receiver supports all mandatory and many optional 3D
formats. It supports HDTV formats up to UXGA at 8 bit.
The HDMI-compatible receiver on the ADV7611 incorporates
programmable equalization of the HDMI data signals. This
equalization compensates for the high frequency losses inherent
in HDMI and DVI cabling, especially at longer lengths and higher
frequencies. It is capable of equalizing for cable lengths up to
30 meters to achieve robust receiver performance.
With the inclusion of HDCP, displays can receive encrypted
video content. The HDMI interface of the ADV7611 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.
The ADV7611 has a synchronization regeneration block used
to regenerate the DE based on the measurement of the video
format being displayed and to filter the horizontal and vertical
synchronization signals to prevent glitches. The HDMI receiver
also supports TERC4 error detection, used for detection of
corrupted HDMI packets following a cable disconnect.
The HDMI receiver contains an audio mute controller that
can detect a variety of conditions that may result in audible
extraneous noise in the audio output. On detection of these
conditions, the audio signal can be ramped to prevent audio
clicks or pops. Audio output can be formatted to LPCM and
IEC 61937.
The HDMI receiver features include:
• 162.5 MHz (UXGA at 8 bit) maximum TMDS clock
frequency
• 3D format support defined in HDMI 1.4a specification
• Integrated equalizer for cable lengths up to 30 meters
• HDCP 1.4
• Internal HDCP keys
• PCM audio packet support
• Repeater support
• Internal EDID RAM
• Hot Plug assert output pin for an HDMI port
• CEC controller
COMPONENT PROCESSOR
The ADV7611 has an any-to-any 3 × 3 CSC matrix. The CSC
block is placed at the back of the CP section. CSC enables
YPrPb-to-RGB and RGB-to-YCrCb conversions. Many other
standards of color space can be implemented using the color
space converter.
CP features include:
• 525i, 625i, 525p, 625p, 720p, 1080i, 1080p, and other
formats
• Manual adjustments including gain (contrast) and
offset (brightness), hue, and saturation
• Free run output mode that provides stable timing when no
video input is present
• 162.5 MHz processing rate
• Contrast, brightness, hue, and saturation controls
• Standard identification enabled by STDI block
• RGB that can be color space converted to YCrCb and
decimated to a 4:2:2 format for video-centric back end IC
interfacing
• DE output signal supplied for direct connection to an
HDMI/DVI transmitter
OTHER FEATURES
The ADV7611 has HS, VS, FIELD, and DE output signals with
programmable position, polarity, and width.
The ADV7611 has programmable interrupt request output pins,
including INT1 and INT2 (INT2 is accessible only via one of
following pins: MCLK/INT2, SCLK/INT2, or HPA_A/INT2).
It also features a low power-down mode. The I2C address of
the main map is 0x98 after reset. This can be changed after reset
to 0x9A if pullup is attached to VS/FIELD/ALSB pin and I2C
command SAMPLE_ALSB is issued. Refer to the Register
Access and Serial Ports Description section in the UG-180.
The ADV7611 is provided in a 10 mm × 10 mm, RoHS-compliant
LQFP_EP package, and is specified over the −40°C to +85°C
temperature range.
