2 / 104 page  FS401, FS403 PRODUCT SPECIFICATION REV. NO. 1.7 2 JANUARY 24, 2007 COPYRIGHT © 1999, 2000, 2003 FOCUS ENHANCEMENTS, INC. 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 automatically 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. Power is derived from +3.3V digital and analog supplies. Packages are 100-lead (FS401) or 128-lead (FS403) Plastic Quad Flat Pack (PQFP).
