HDMI transmitter features on-chip consumer electronic control support

Norwood, Mass.—Analog Devices' ADV7520NK is a low-power HDMI v1.3 transmitter for portable media and DVD players, video recorders, and other mobile multimedia devices capable of supporting high-definition audio and video content.

According to ADI, 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.

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.

The ADV7520NK adds CEC support to the low-power design of ADI's AD9387NK HDMI transmitter, which enables longer-running battery-powered video devices. ADI's 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.

Pricing: $4.13 per unit in 1,000-unit quantities.
Availability: Sampling; full production quantities in November 2007.
