Example 3
4.3.1
Assumptions
Input connector:
Component [VI_1_B (Pb), VI_2_B (Y), VI_3_B (Pr)]
Video format:
NTSC (J, M, 443), PAL (B, G, H, I, M, N, Nc) and SECAM
Output format:
20-bit 4:2:2 YCbCr with discrete sync outputs
4.3.2
Recommended Settings
Recommended I2C writes: This setup requires additional writes to output the discrete sync 20-bit 4:2:2 data, HS, and
VS, and to autoswitch between all video formats mentioned above.
I2C register address 00h = Input select register
I2C data 95h = Sets Pb to VI_1_B, Y to VI_2_B, and Pr to VI_3_B
I2C register address 04h = Autoswitch mask register
I2C data 3Fh = Includes NTSC 443 and PAL (M, Nc) in the autoswitch
I2C register address 08h = Luminance processing control 3 register
I2C data 00h = Optimizes the trap filter selection for NTSC and PAL
I2C register address 0Eh = Chrominance processing control 2 register
I2C data 04h = Optimizes the chrominance filter selection for NTSC and PAL
I2C register address 33h = Output formatter 1 register
I2C data 41h = Selects the 20-bit 4:2:2 output format
I2C register address 34h = Output formatter 2 register
I2C data 11h = Enables YCbCr output and the clock output
I2C register address 36h = Output formatter 4 register
I2C data AFh = Enables HS and VS sync outputs
