Deep Color HDMI Transmitter Integrates CEC Controller And Buffer

According to the company, the Analog Devices ADV7510 is the first Deep Color HDMI transmitter in the industry to integrate a consumer electronic control (CEC) controller and buffer for high-definition audio/video devices. As part of ADI’s Advantiv advanced television solutions portfolio, it reduces component count, eases design complexity, and reduces time-to-market for audio/video receivers, Blu-ray players, high-performance set-top boxes, digital video recorders, and video game consoles.

While competitive products require a separate CEC controller, the ADV7510’s on-chip controller speeds the CEC and HDMI certification process while reducing board space by 20%. The device also is backed by ADI’s field-tested software driver and HDMI pre-certification testing, further reducing time-to-market. It provides 12-bt Deep Color operation and 1080p connectivity as well.

The Deep Color technology increases the number of colors that can be displayed on video devices, allowing the display of millions of distinct colors. This allows gradual changes in hue or brightness and makes pictures appear smoother and more lifelike. The HDMI transmitter also supports x.v.Color, which increases the range of available colors to render the most realistic images possible when playing digital video content.

By including on-chip high-bandwidth digital content protection (HDCP), the ADV7510 implements the functions of HDMI repeater applications that prevent unauthorized recording, ensuring HDCP authentication without delay. The device also helps reduce system cost by incorporating an I2C master for extended display identification data (EDID) reading and 5-V tolerant I/Os that support I2C and Hot Plug Detect (HPD).

The transmitter supports S/PDIF for linear pulse-code modulation (LPCM) or compressed audio, including Dolby Digital, DTS, and THX. With eight-channel I2S audio support, it also enables stereo or 7.1-channel surroundsound audio up to 768 kHz. Up to eight channels of direct stream digital (DSD) are available to support the latest high-definition audio standards as well.

The ADV7510 is fabricated on an advanced CMOS process and comes in a 14- by 14-mm, 100-lead lead-frame chip-scale package (LQFP). It is specified from –25°C to 85°C. Available now, it costs $7.59 each in 1000-unit quantities.
