FS403 General Description

The FS400 family is a fourth generation video scan converter. It accepts many input resolutions and rates and converts them to NTSC or PAL standards compliant with SMPTE-170M and CCIR-656 standards. Also available as output options are VGA 640 x 480 at 60Hz progressive, SVGA 800 x 600 at 60Hz progressive, and 100 Hz interlaced. The chip has a programmable down scaler to fit the incoming resolution to the output display format. Within the FS400 are capture and encode r engines separated by the frame buffer memory controller. Required external components are minimal: a single 16M SDRAM memory, clocks and passive parts.

Analog progressive RGB inputs are digitized and converted to the YUV 4:2:2 format. Vertical scaling and flicker filtering are implemented at the computer frame rate ahead of the frame store interface.

Interlaced input is supported for XGA resolution and above. In this mode, only the first field is processed.

The Flicker Filter is an advanced 2 dimensional filter that enhances text quality. Flicker Filter parameters are programmable to allow user tradeoffs between flicker and sharpness.

The FS400 family contains controls for programmable sharpness, brightness, contrast, and color saturation. These controls allow output to be tuned to match user desires and tastes.

Frame rate conversion is implemented by a Frame Store Controller that interfaces with an external SDRAM frame store memory.

YUV 4:2:2 data is recovered from the memory at the outgoing frame rate. Data is scaled prior to the digital video encoder that generates Y/C and Composite Video outputs. For RGB and YUV outputs, the encoder may be bypassed via a YUV to RGB transcoder for SCART compatible video, and for output to VGA or SVGA displays.

The FS400 has built in capability to automatically detect the incoming video mode and automatically select optimal sampling and scaling parameters. The chip can detect the location of the active video in the input, and can utomatically center the input on the TV screen. All parameters can be read and written via the SIO serial port.

The FS403 has support for glueless integration with Zilog and Philips On Screen Display (OSD) microcontrollers. The OSD interface allows a customized on screen user interface that can contain opaque or halftone video backgrounds.

The FS403 has direct digital inputs, bypassing the built-in ADCs.

The FS402 incorporates Macrovision 7 anti copy protection technology.

Power is derived from +3.3V digital and analog supplies. Packages are 100-lead (FS401 and FS402) or 128-lead (FS403) Plastic Quad Flat Pack (PQFP).
