CH7016A SDTV / HDTV Encoder
Features
GENERAL DESCRIPTION
• VGA to SDTV conversion supporting graphics
The CH7016A is a Display Controller device which accepts
resolutions up to 1024x768
a digital graphics input signal, and encodes and transmits data
• Analog YPrPb output for HDTV
through a 10-bit high speed DAC. The device is able to
• HDTV support for 480p, 576p, 720p, 1080i and 1080p encode the video signals and generate synchronization signals
• Programmable digital input interface supporting RGB for NTSC and PAL TV standards (SDTV), as well as analog
and YCrCb input data formats
HDTV interface standards and graphics standards up to
• True scale rendering engine supports under-scan in all UXGA. The device accepts data over one 12-bit wide
TV output resolutions
variable voltage data port which supports 5 different data
• Text enhancement filter
formats including RGB and YCrCb.
• Adaptive flicker filter with up to 7 lines of filtering
• Interlaced to progressive scan conversion for DVD The TV-Out processor will perform non-interlace to interlace
• Support for NTSC, PAL and HDTV formats
conversion with scaling and flicker filter, and encode data into
• Support for SCART connector
any of the NTSC or PAL video standards. The scaling and
• Outputs CVBS, S-Video, RGB and YPrPb
flicker filter is adaptive and programmable to enable superior
• Support for Wide Screen Signaling (WSS)
text display. Eight graphics resolutions are supported up to
• TV / Monitor connection detect
1024 by 768 with full vertical and horizontal under-scan
• Programmable power management
capability in all modes. A high accuracy low jitter phase
• Four 10-bit video DAC outputs
locked loop is integrated to create outstanding video quality.
• Fully programmable through serial port
ITU-R BT.656 interlaced video can also be input and scan
• Complete Windows and DOS driver support
converted to non-interlaced video.
• Low voltage interface support to graphics device
• Offered in a 48-pin LQFP package
In addition to TV encoder modes, bypass modes are included
which perform color space conversion to HDTV standards
and generate and insert HDTV sync signals, or output VGA
style analog RGB for use as a CRT DAC.
