Analog Devices’ ADV7520NK is a low-power HDMI™ v1.3 (High-Definition Multimedia Interface™) transmitter for portable media and DVD players, video recorders, and other mobile multimedia devices capable of supporting high-definition audio and video content. The ADV7520NK is the first HDMI transmitter to incorporate a CEC (Consumer Electronic Control) buffer on-chip, which reduces component count, eases design complexity and speeds time to market for portable high-definition (HD) devices by eliminating the need for the design engineer to develop a separate CEC support channel.

Providing added convenience, the CEC feature allows end users to use a single remote control to run multiple CEC-enabled HD devices, eliminating the need to juggle separate remotes to control the TV, set-top box and portable HD devices. For example, when viewing content from an HD DVC, DSC, or portable media player on an HDTV the CEC-enabled HDTV remote can be used to play or rewind movies, manage power-on, input selection and power-off functions for the TV, cable/satellite set-top box or audio/video receiver, switch between boxes, or change video and audio modes.

The ADV7520NK adds CEC support to the innovative low-power design of ADI’s AD9387NK HDMI transmitter, which enables longer-running battery-powered video devices. Unlike competitive devices that can require external voltage translator chips, ADI’s new HDMI transmitter includes 5 V-tolerant I/Os that support I²C and HPD (Hot Plug Detect). This further simplifies system design and extends battery life in portable electronics by eliminating external voltage translator chips to convert these I/O signals from 5 V to either 1.8 V or 3.3 V.

The new HDMI transmitter includes support for xvYCC (known as “extended view” or “extended Gamut YCC” as specified in IEC 61966-2-4) color gamut metadata, which increases the range of available colors to render the most life-like images possible when playing back digital video content. The ADV7520NK supports HDMI v1.3, DVI (Digital Video Interface) v1.0, and HDCP v1.3 standards as well as S/PDIF (Sony/Philips Digital Interface Format) and eight channels of I2S (Inter-IC Sound) audio to enable 7.1 surround sound audio with a max sample rate of 192 kHz.

The ADV7520NK HDMI transmitter is compatible with other Analog Devices components in the advanced TV signal chain, including the AD9388A 10-bit dual analog/HDMI receiver; AD7142 programmable capacitance touch screen sensors; and ADV7180 and ADV7441 video decoders.
