Each device announced today extends ADI’s Advantiv® advanced TV solutions portfolio by offering an on-chip 24-bit video interface that supports existing SOC (systems-on-chip) designs, further reducing time-to-market and design costs. The ADV7525 and ADV7526 support HDTV formats up to 720p60f/1080i and 1080p/60f at 1.8 V, making them effective for ultra-slim, power-sensitive handheld designs, including mobile phones, gaming consoles, portable media players, mobile Internet devices, digital still and DSLR cameras and camcorders.
“By incorporating support for HDMI Version 1.4 specification’s 3-D display resolutions and extended colourimetry and a 24-bit video interface on a single chip, these transmitters are the first to close the HD performance gap between ultra-slim, multimedia devices and home entertainment systems,” said Charles O’Roark, product line director, Digital Video Products, Analog Devices.
Complete with internal enhanced CEC (consumer electronic control) with expanded message buffer, 5-V tolerant I/Os and on-chip I²C master, the highly integrated, energy-saving transmitters provide designers with system-ready solutions that lower development and manufacturing costs across a wide range of HDMI-enabled devices.
The ADV7525 and ADV7526 offer complete audio support of S/PDIF (Sony/Philips digital interface format) for compressed audio, including Dolby Digital® and DTS®; and 8-channel I2S audio for transmitting stereo at sample rates up to 192 kHz. With the inclusion of embedded support for HDCP 1.3 (high-bandwidth digital content protection) processing, the transmitters allow the secure transmission of protected content.
Validated through successful compliance testing, the ADV7525 and ADV7526 transmitters are software-compatible with previous video products, including the ADV7521NK low-power HDMI transmitter and ADV7523A/ADV7524A low-power HDMI transmitter . The new transmitters complement other Analog Devices video transmitter components, including the AD9394 5V charge pump HDMI transmitter companion chip, ADV7390/1/2/3 low-power, chip-scale 10-bit SD/HD video encoder and ADV7123 and ADV7125 triple high-speed video DACs (digital-to-analog converters).
