terawins T101A

The T101A is a highly integrated All-in-one Visual Processor that provides major cost saving solution for the portable applications. T101A has built-in high performance Triple ADCs, TCON, Scaling Machine with sophisticated upscaling and downscaling algorithms. The innovative integrated “Frame-Buffer-Less” De-interlacer can significantly reduce system cost. The T101A also integrates On Screen Display engine with 3K-DW of font RAM. The device can interface to an external micro-controller through 2-wire serial bus interface

Application

Portable AV system
Portable TV set
Progressive Car TV set
