General Description
The IP00C702 (SCREEN2) is a high-speed device for real-time image scaling and frame rate
conversion up to SXGA resolution. The IP00C702 supports all the critical functions required in any
display control logic: image scaling, frame rate conversion and de-interlacing. Ideally suited for
high-speed resolution conversion applications, the IP00C702 uses a programmable pixel
interpolation algorithm for producing images of the highest quality.
The IP00C702 can be used in a wide variety of applications, thanks to its very flexible architecture
that supports both standard and custom image formats. With independent clock and
synchronization signals for the input and output ports, the IP00C702 can perform image scaling
even when the input and output images have different frame rates.
