MSD7851L-LF MSTAR TQFP256

The MSD7851L is a highly integrated, low-cost and high performance SoC for cable, satellite, terrestrial, and IP
client high-definition STB (Set-Top Box) applications with conditional access (CA). It is configured with a
transport stream processor with different types of descrambler needed for different CA systems, a smartcard
interface, a multi-format audio, and video decoder which is capable of decoding MPEG-1/2/4, H.264 (ISO/IEC
14496-10), VC-1, AVS, RealMedia formats, and a DVB-CI/CI+ interafce. It has a digital video encoder of
supporting CVBS, S-Video, YPbPr SD, and HD output. For HD digital output, the MSD7851L also has a built-in
HDMI 1.3 transmitter.

For conditional access (CA) and digital right management (DRM) applications, the MSD7851L provides a very

secure architecture for protecting any security information in a CA/DRM system. It provides a secure boot
loader including a programmable OTP ROM, a hardware-controlled key management unit that can fulfill the
requirements from different CA and DRM systems.

For multimedia and network applications, the MSD7851L includes two USB 2.0 host and one USB 2.0

device/host controller, a 10/100 Mbps Ethernet controller, a SDIO controller making it possible for the
MSD7851L to decode and record media files via those sources from both network and external storage devices.
With built-in high performance MIPS34K CPU and DDR2 SDRAM controller, the MSD7851L can fulfill the
requirement of modern multimedia and network applications.
