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
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
Parallel: 27 MHz Pixel clock
NTSC: 60 fields/sec
PAL: 50 fields/sec
Two-wire I/F for register interface plus high-level command exchange. SPI port to
interface to external memory to load overlay data, register settings, or firmware
extensions.
27 MHz
1.6875 – 18 MHz, programmable
Analog: 2.8 V + 5%
Core: 1.8 V + 5% (2.8 V + 5% power supply with off-chip bypass transistor generates a
1.70 − 1.95 V core voltage supply, which is acceptable for performance.)
IO: 2.8 V + 5%
Full resolution at 60 fps: 291 mW
Full resolution at 60 fps: 192 mW
