Typical Value
Utilizes SPI interface to load overlay data from external flash/EEPROM memory with the
following features:
•Available in Analog output and BT656 Digital output
•Overlay Size 360 x 480 pixel rendered into 720 x 480 (NTSC) or 720 x 576 (PAL)
•Up to four (4) overlays may be blended simultaneously
•Selectable readout: Rotating order user-selected
•Dynamic scenes by loading pre-rendered frames from external memory
•Palette of 32 colors out of 64,000
•8 colors per bitmap
•Blend factor dynamically-programmable for smooth transitions
•Fast update rate of up to 30 fps
•Every bitmap object has independent x/y position
•Statistic Engine to calibrate optical alignment
•Number Generator
Programmable to any size
0.5–16x
10-bit, on-chip
Analog composite video out, single-ended or differential; 8-, 10-bit parallel digital output
Digital: Raw Bayer 8-,10-bit, CCIR656, 565RGB, 555RGB, 444RGB
