PW181
Product Specification
General Description
The PW181 ImageProcessor is a highly integrated
Crystal
?system-on-a-chip? that interfaces computer graphics and
video inputs in virtually any format to a fixed-frequency flat
panel display.VideoVideo
Decoder
Input
Computer and video images from NTSC/PAL to WUXGA PW181Display
at virtually any refresh rate can be resized to fit on a fixed-ADC/
Computer
TMDS
frequency target display device with any resolution up to
WUXGA. Video data from 4:3 aspect ratio NTSC or PAL
and 16:9 aspect ratio HDTV or SDTV is supported. Multi-PW181ROM
region, nonlinear scaling allows these inputs to be resized System Block Diagram
optimally for the native resolution of the display.
Advanced scaling techniques are supported, such as
format conversion using multiple programmable regions.
