1 FEATURES
1.1 RGB video input
• Digital single (24-bit) or dual (48-bit) channel RGB input
• Data input of sampled RGB data with a pixel frequency
of maximum 150 MHz
• Free definable data acquisition offsets and vertical
window size in single pixel increments, horizontal
window size in double pixel increments
• Programmable pulses for ADC clamping and ADC gain
correction
• Detection of presence of sync signals, and of their
polarities
• Support for auto-adjustment functions for sample clock
frequency, phase, vertical and horizontal sample offset,
as well as colour adjustment
• Maximum supported resolution of 1280 × 1024 dots
Super Extended Graphics Adapter (SXGA)
• Support for detection of the applied graphics mode
(auto-scan).
1.2 Video processing
• Colour correction Look-Up Table (LUT)
• Phase correct up and downscaling of the RGB data
• Fully programmable scaling ratios
• Independent horizontal and vertical scaling engine
• Free definable position of the scaled input picture inside
the output picture with programmable border colour.
1.3 On screen display
• Character based internal On Screen Display (OSD)
• Programmable character matrix sizes of either
24 × 24 pixels (42 characters available) or
12 × 16 pixels (128 characters available)
• Programmable width and height of the OSD window,
built from maximum 1152 characters
• 8 different colours for foreground and background
inclusive transparent colours
• Overlay port for external OSD controller.
1.4 Video output
• Single pixel/clock (24-bit) or double pixel/clock (48-bit)
digital RGB output
• Generation of synchronization and validation signals for
the Thin Film Transistor (TFT) display
• Frame rate control (temporal dithering) for displaying
true colour graphics on high colour displays
• Free programmable timing for displays of several
manufacturers.
1.5 Memory interface
• Support of both 1M × 16 SDRAM, 256k × 32 SGRAM or
128k × 32 SGRAM devices
• Maximum memory clock frequency of 125 MHz
• Scalable memory size built of either 2, 3 or 4 SDRAM,
or of 1 or 2 SGRAM devices
• Special mode for operation without external memory.
1.6 Miscellaneous
• Internal Phase-Locked Loop (PLL) for memory and
panel clock generation from the system clock
• I2C-bus interface with 2 selectable addresses
• Boundary scan test circuit and Joint Test Action Group
(JTAG) test controller
• Pin compatible to SAA6721E
• Programming compatible to SAA6721E.
