Intersil公司的ISL34340是LVCMOS的并行视频数据串化器和解串器,它能把加在并行LVCMOS总线上的信号转换成串行高速差分信号,而在远端通过解串器又把这差分信号转换回并行视频信号,广泛应用在导航和显示系统,视频娱乐系统,工业计算终端以及遥控照相机.本文介绍了ISL34340的主要性能,方框图,应用方框图以及ISL34340评估板的详细电路图.
The ISL34340 is a serializer/deserializer of LVCMOS parallel video data. The video data presented to the serializer on the parallel LVCMOS bus is serialized into a high-speed differential signal. This differential signal is converted back to parallel video at the remote end by the deserializer. It also transports auxiliary data bidirectionally over the same link during the video vertical retrace interval.
ISL34340主要特性:
24-bit RGB transport over single differential pair
Bidirectional auxiliary data transport without extra bandwidth and over the same differential pair
40MHz PCLK transports
-SVGA 800x600 @ 70fps, 16% blanking
-WSVGA 1024x600 @ 60fps, 8% blanking
Internal 100Ω termination on high-speed serial lines
DC balanced 8b/10b line code allows AC-coupling
Provides immunity against ground shifts
Transmitter amplitude boost and pre-emphasis and receiver equalization allow for longer cable lengths and higher data rates
Same device for serializer and deserializer simplifies inventory
I2C interface
High-speed serial lines meet 8kV ESD rating
Pb-free (RoHS compliant)
ISL34340应用:
Navigation and display systems
Video entertainment systems
Industrial computing terminals
Remote cameras
