SAA7140A; SAA7140B High Performance Scaler (HPS)

The SAA7140A and SAA7140B are CMOS High Performance Scaler (HPS) and is a highly integrated circuit designed for use in DeskTop Video (DTV) applications. The devices resample digital Video signals using two dimensional phase-correct interpolation in order to Display it in an arbitrarily sized window. The SAA7140A fits perfectly into a 5 V signal environment and requires two different supply voltages (5 V and 3.3 V). The SAA7140B is a pure 3.3 V design and therefore has only 3.3 V supply pins. With respect to functions and programming, both devices are identical.The devices incorporate additional functions such as control of brightness, saturation, contrast, chroma key generation, YUV-to-RGB conversion, compensation of gamma precorrection, dithering and choice of several output formats. The SAA7140A and SAA7140B accepts data from 1 or 2 input signal sources, via it,s 16-bit YUV input port and/or the bidirectional expansion port. They deliver scaled data on the 32-bit VRO output port and, if selected, also on the bidirectional expansion port. A synchronous (transparent) together with an asynchronous (burst) data transfer mode is supported at the 32-bit VRO port.
