Analog Devices intros new HDMI transmitter

BANGALORE, INDIA: Analog Devices has announced the launch of its ADV7520NK, a low-power HDMI v1.3 (High-Definition Multimedia Interface) transmitter for portable media and DVD players, video recorders, and other mobile multimedia devices.

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, Analog Devices said in a statement.

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.

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.

It also supports 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 is sampling now, and will be available in full production quantities in November 2007. It is priced at $4.13 per unit in 1,000-unit quantities and is available in a 76-ball BGA (ball grid array) package or a 64-lead LFCSP (lead-frame chip-scale package).
