4 Example Register Settings
The following example register settings are provided only as a reference. These settings, given the assumed input
connector, video format, and output format, set up the TVP5146 decoder and provide video output. Example register
settings for other features and the VBI data processor are not provided here.
4.1
Example 1
4.1.1
Assumptions
Input connector:
Composite (VI_1_A) (default)
Video format:
NTSC (J, M), PAL (B, G, H, I, N) or SECAM (default)
NOTE: NTSC-443, PAL-Nc, and PAL-M are masked from the autoswitch process by default.
See the autoswitch mask register at address 04h.
Output format:
10-bit ITU-R BT.656 with embedded syncs (default)
4.1.2
Recommended Settings
Recommended I2C writes: For the given assumptions, only one write is required. All other registers are set up by
default.
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 3 register
I2C data 04h = Optimizes the chrominance filter selection for NTSC and PAL
I2C register address 34h = Output formatter 2 register
I2C data 11h = Enables YCbCr output and the clock output
NOTE: HS/CS, VS/VBLK, AVID, FID, and GLCO are logic inputs by default. See output
formatter 3 and 4 registers at addresses 35h and 36h, respectively.
