3.3. PW1306
The PW1306 Video Image Processor is a “system-on-a-chip ” that oversamples and processes RGB or YPbPr video from
analog video decoders. The PW1306 integrates video processing, including deinterlacer and video enhancement filters with a
triple ADC. Analog RGB or YPbPr in PC graphics, standard, or high-definition video can be displayed in either 4:3 or 16:9
formats.
•
Supports analog video decoders with triple 8-bit Analog-to-Digital Converters (ADCs) up to 140 MSPS conversion rate
•
Supports Sync-on-Green (SOG), Sync-on-Luma (SOY),and Composite sync inputs
•
1080i/720p/480p HDTV; 480i and 576i NTSC/PAL SDTV; PC graphics (up to SXGA)
•
YPbPr/YCbCr/YUV-to-RGB Color Space Converter with programmable coefficients
•
On-chip, bitmap-based, OSD controller with on-chip memory
•
24/30/48-bit RGB output with 135 MPixels/second maximum output rate
