Intersil ISL5960x MegaQ视频均衡解决方案
Intersil 公司的MegaQ ISL5960x系列是单路自适应视频均衡器,适用于长达1600米的Cat 5/6电表缆和长达6000英尺(1800米)的RG-59电缆,可以补偿电缆损耗达60dB,源放大变化±3dB.器件单电源5V工作,能为两个75欧姆负载提供2VP-P输出,能和彩色或单色,NTSC或PAL信号兼容,主要应用在视频监视和视频分配.本文介绍了ISL5960x系列主要特性,方框图, 典型应用电路图以及ISL59605-SPI-EVALZ评估板电路图和材料清单.
The ISL59601, ISL59602, ISL59603, ISL59604, and ISL59605 (the “MegaQ™” product family) are single-channel adaptive equalizers designed to automatically compensate for long runs of Cat 5/6 or RG-59 cable, producing high quality video output with no user interaction. The ISL59601 equalizes Cat 5/6 up to a distance of 1000 feet (300 meters), while the ISL59605 equalizes up to 5300 feet (1600 meters).
MegaQ™ compensates for high frequency cable losses of up to 60dB (ISL59605) at 5MHz as well as source amplitude variations up to ±3dB.
The ISL59601, ISL59602, ISL59603, ISL59604, and ISL59605 operate from a single +5V supply. Inputs are AC-coupled and internally DC-restored. The output can drive 2VP-P into two source-terminated 75Ω loads (AC-coupled or DC-coupled).
ISL5960x主要特性:
• ISL59605 Equalizes Up to 1 Mile (1600m) of Cat 5/6 and Up to 6000 Feet (1800m) of RG-59
