| MPEG-2 HD/SD STB SoC----CSM1100 |
| The CSM1100 is a highly-integrated SoC that supports high definition and standard definition satellite, cable, terrestrial DTV Set-Top-Box (STB) applications. It improves previous generation STB chipset solutions in video quality, processor performance, 2-D graphic engine enhancement, software audio decoder with multiple bit rate and peripheral support. An embedded ARM processor running at 220MHz can support the advanced embedded software applications such as middleware, MHP and EPG. The CSM1100 is built in 0.13¦Ìm process technology. It has very low power consumption. The BGA package and ball assignment are designed for easy board layout and reducing system cost. |
