The MT5325ZLHJ family is a back end decoder and a TV
controller and offers high integration for advanced
applications. It combines a transport de-multiplexer, a high
definition video decoder, an AC3 audio decoder, a four-link
LVDS transmitter, a mini-LVDS transmitter, a V-by-One
transmitter, and an NTSC/PAL/SECAM TV decoder with a 3D
comb filter (NTSC/PAL).
