This application note discusses about Pericom’s full line of video switches. Pericom provides a full line of video switches with high performance, low crosstalk and fast switching time. The PI3Vxx and PI5Vxx video switch families are suitable for all types of analog video signal applications and providing an optimum cost-performance solution. These solutions make Pericom the leader in the video signal switch markets.
Pericom PI3Vxx and PI5Vxx families are wide-bandwidth Video Switches specifically designed and characterized for analog video signal applications, including the component video signals of Ypbpr, YUV, YIQ, Y/R-Y/B-Y, RGB, and the composite video signals such as NTSC, PAL, SECAM etc. Because of the low on-resistance and on-capacitance, the PI3Vxx and PI5Vxx families have high bandwidth. For example, the insertion loss (bandwidth) is -3.22 db at 1Ghz for PI3V520 and is -3.39 db at 570 Mhz for PI5V330S. The PI3Vxx and PI5Vxx families also have good R-on flatness, which is an important analog characteristic for video signals that request minimum distortion due to the critical color and picture quality request. The low crosstalk of the PI3Vxx and PI5Vxx family will ensure the high quality display for the high definition video signals. The PI3Vxx and PI5Vxx families are the NMOS switches. Therefore, when the Vdd power is off, the input channels of these switches will be high impedance. Thus, these video switches are hot swappable to fulfill the TV video signal switching applications. The excellent performance and low cost of the PI3Vxx and PI5Vxx families provide an optimum cost-performance solution to high volume video applications. Many major manufacturers are using the PI3Vxx and PI5Vxx families for variety applications, such as projection TV, LCD TV, FPD, PDP and HDTV.
