VIDEO DECODER

T132AV

The T132AV is a highly integrated All-in-one Visual Processor that provides major cost saving solution for the portable applications. T132AV has built-in high performance triple ADCs, TCON, triple DACs, Scaling Machine with sophisticated upscaling and downscaling algorithms. The innovative integrated “Frame-Buffer-Less” De-interlacer can significantly reduce system cost. The T132AV also integrates On Screen Display engine with 3K words of font RAM and built-in 1K words of font ROM. The device can interface to an external micro-controller through 2-wire serial bus interface.
