Intersil公司的ISL59450是视频输入交叉接点开关,支持多格式视频,包括CVBS, S-Video, YPbPr, 和RGB信号. ISL59450嵌入的抗混淆滤波器具有可编程的拐点频率,从而消除了来自视频DAC的干扰尖峰.可编程的增益x1或 x2,广泛应用在AV接收器,LCD TV,AV交换箱,投映仪,HDTV系统和多个视频输入系统.本文介绍了ISL59450的主要特性, 功能方框图以及分量视频方框图, S视频方框图, 复合视频方框图和分离器方框图, 应用电路图.
The ISL59450 is a video crosspoint switch supporting multiple video input formats (CVBS, S-Video, YPbPr, and RGB signals). Embedded anti-aliasing filters with programmable corner frequencies eliminate glitch noise from video DACs. The large number of inputs, wide range of formats, integrated anti-aliasing filters, and dual sync-separators make the ISL59450 an ideal choice for video switching in nearly all display systems.
The ISL59450 is available in a 128 Ld MQFP package and is specified for operation over the full -40°C to +85°C temperature range.
ISL59450主要特性:
6 Composite, 4 S-Video and 4 Component Video Sources 2 Component Inputs can be Configured for VGA with Separate H and V Sync Inputs Multi-format Video Filtering Compatible with Macrovision® Encoded Signals Programmable Gain of x1 or x2 Outputs have High Impedance Disable Mode Two Universal Sync Separators support SD, HD, and Computer Signals Pb-free (RoHS compliant)
应用: AV Receivers LCD-TVs AV Switch Boxes Projectors HDTV Systems Multiple Video Input Systems
