INDUSTRY'S FIRST HDMI TRANSMITTER TO FEATURE ON-CHIP CONSUMER ELECTRONIC CONTROL SUPPORT

Analogs’ ADV7520NK is a HDMI v1.3 transmitter for portable media and DVD players, video recorders, and other mobile multimedia devices supporting high-definition audio and video content.

ADV7520NK simplifies portable HDMI product design by integrating consumer electronic control functions allowing end users to command multiple A/V devices with one remote.

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 3.3V
