ADV7612在兩個輸入HDMI端口具有高質(zhì)量的Xpressview快速交換.主要用在投映儀,視頻會議,汽車電子,HDTV,AVR和STB,條形音響和視頻交換.本文介紹了ADV7612 HDMI接收器和ADV7511 HDMI發(fā)送器主要特性, ADV7612功能和內(nèi)核方框圖,以及EVAL-ADV7612-7511視頻評估板框圖,電路圖,材料清單和PCB布局圖. The ADV7612 is offered in automotive, professional (no HDCP), and industrial versions. The operating temperature range is −40℃ to +85℃. The ADV7612 is a high quality Xpressview™ fast switching HDMI®-capable receiver. It incorporates a dual input HDMI-capable receiver that supports all mandatory 3D TV formats defined in HDMI 1.4a specification, HDTV formats up to 1080p 36-bit Deep Color, and display resolutions up to UXGA (1600 × 1200 at 60 Hz). It integrates a CEC controller that supports the capability discovery and control (CDC)The ADV7612 incorporates Xpressview fast switching on both input HDMI ports. Using Analog Devices, Inc., hardware-based HDCP engine that minimizes software overhead, Xpressview technology allows fast switching between both HDMI input ports in less than 1 second. Each HDMI port has dedicated 5 V detect and Hot Plug™ assert pins. The HDMI receiver also includes an integrated program-mable equalizer that ensures robust operation of the interface with long cables. The ADV7612 offers a flexible audio output port for audio data extraction from the HDMI stream. HDMI audio formats, including SACD via DSD and HBR, are supported by ADV7612. The HDMI receiver has advanced audio functionality, such as a mute controller that prevents audible extraneous noise in the audio output. Additionally, the ADV7612 can be set to output TDM I2S, which provides four multiplexed I2S channels. The ADV7612 contains one main component processor (CP) that processes the video signals from the HDMI receiver. It provides features such as contrast, brightness and saturation adjustments, STDI detection block, free run, and synchronization alignment controls. Fabricated in an advanced CMOS process, the ADV7612 is provided in a 14 mm × 14 mm, 100-lead surface-mount LQFP_EP, RoHS-compliant package, and is specified over the −40°C to +85°C temperature range. ADV7612 HDMI接收器主要特性: High-Definition Multimedia Interface (HDMI) 1.4a features supported All mandatory and additional 3D video formats supported Extended colorimetry, including sYCC601, Adobe RGB, Adobe YCC 601, xvYCC extended gamut color CEC 1.4-compatible HDMI receiver 225 MHz maximum TMDS clock frequency Xpressview fast switching of HDMI ports 36-/30-bit Deep Color and 24-bit color support High-bandwidth Digital Content Protection (HDCP) 1.4 support with internal HDCP keys HDCP repeater support Up to 127 KSVs supported Integrated CEC controller Programmable HDMI equalizer 5 V detect and Hot Plug assert for each HDMI port Audio support Audio support including high bit rate (HBR) and direct stream digital (DSD) S/PDIF (IEC 60958-compatible) digital audio support Supports up to four I2S outputs and time-division multiplexed (TDM) I2S Advanced audio mute feature Dedicated, flexible audio output port Super audio CD (SACD) with DSD output interface HBR audio Dolby® TrueHD DTS-HD Master Audio™ General Interrupt controller with two interrupt outputs Standard Identification (STDI) circuit Highly flexible 36-bit pixel output interface Internal EDID RAM Any-to-any 3 × 3 color space conversion (CSC) matrix 2-layer PCB design supported 100-lead LQFP_EP, 14 mm × 14 mm package Qualified for Automotive Applications ADV7612主要應(yīng)用: Projectors Automotive Video conferencing HDTVs AVR, HTiB Soundbars Video switches
