CXAS42218是一款超低功耗、高带宽的视频交换机，专门用于交换三种模拟视频信号，包括计算机RGB和高清晰度YPbPr信号。开关的宽频带（350MHz）允许信号以最小的边缘和相位失真通过，而-60dB的非相邻信道串扰在有源信道之间产生可忽略的图像噪声。优化的差分增益和相位保持了视频应用的图像完整性，而低导通电阻提供低信号插入损耗。
•供电范围：2.5V至5.5V
•导通电阻：5.0V时为7Ω（典型值）
•高-3dB带宽：350MHz
•高隔离度：30MHz时为-47dB
•非相邻信道串扰：30MHz时为-60dB
•通道间接地，以优化隔离和
减少恶意串扰

产品概述 返回TOP
The CXAS42218 is an ultra-low power, high-bandwidth video switch specially designed for switching three analog video signals, including computer RGB and high-definition YPbPr signals. The wide bandwidth (350MHz) of the switch allows signal passage with minimum edge and phase distortion, while -60dB nonadjacent channel crosstalk generates negligible image noise between active channels. Optimized differential gain and phases maintain the image integrity of video applications, while low on resistance offers low signal insertion loss.
The CXAS42218 is available in Green TQFN-3×3-20L and TSSOP-20 packages. It operates over an ambient temperature range of -40℃ to +85℃.
