11 / 16 page Data Sheet ADV7610 Rev. 0 | Page 11 of 16 FUNCTIONAL OVERVIEW HDMI RECEIVER The receiver supports all mandatory and many optional 3D formats. It supports HDTV formats up to UXGA at eight bits. The HDMI-compatible receiver on the ADV7610 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 of 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 ADV7610 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 ADV7610 has a synchronization regeneration block 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 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 eight bits) maximum TMDS clock frequency • 3D format support defined in the HDMI specification • Integrated equalizer for cable lengths of up to 30 meters • HDCP 1.4 • Internal HDCP keys • PCM audio packet support • TDM I2S audio packet support • Repeater support • Internal EDID RAM • Hot Plug assert output pin for an HDMI port • CEC controller COMPONENT PROCESSOR (CP) The ADV7610 has an any-to-any 3 × 3 CSC matrix. The CSC block is placed in the output section of the component processor. The CSC enables YPrPb-to-RGB and RGB-to-YCrCb conversions. Many other standards of colorspace can be implemented using the colorspace 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 videocentric back-end IC interfacing • DE output signal supplied for direct connection to an HDMI/DVI transmitter OTHER FEATURES The ADV7610 has HS, VS, FIELD, and DE output signals with programmable position, polarity, and width. The ADV7610 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 pull-up is attached to the VS/FIELD/ALSB pin and the I2C command SAMPLE_ALSB is issued. The ADV7610 is provided in a 6 mm × 6 mm, RoHS-compliant BGA package and is specified over the −40°C to +85°C temperature range.
