Maxim MAX9291吉比特多媒体串行链接(GMSL)解决方案
Maxim公司的MAX9291/MAX9293是用于同轴电缆或屏蔽双绞线(STP)输出和HDMI输入的3.12Gbps GMSL串行化器,用来在15米或更长的50欧姆同轴电缆或100欧姆屏蔽双绞线上发送视频,音频和控制信号,主要用在高分辨率汽车导航,后座娱乐系统和百万相素照相系统.本文介绍了MAX9291/MAX9293主要特性和优势和功能框图,典型应用电路图以及MAX9291/MAX9293评估板主要特性,电路图,材料清单和PCB设计图.
The MAX9291/MAX9293 GMSL serializers convert an HDMI input to a gigabit multimedia serial link (GMSL) output for transmission of video, audio, and control signals over 15m or more of 50Ω coax or 100Ω shielded twisted-pair (STP) cable. The MAX9293 has HDCP content protection, but is otherwise the same as the MAX9291. The serializers pair with any GMSL deserializer capable of coax input. When programmed for STP output, the serializers are backward compatible with any GMSL deserializer. The output amplitude is programmable 100mV to 500mV single-ended (coax) or 100mV to 400mV differential (STP).
The audio channel supports L-PCM I2S stereo and up to eight channels of L-PCM in TDM mode. Sample rates of 32kHz to 192kHz are supported with sample depth up to 32 bits.
