Example Register Settings

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 TVP5147M1 decoder and provide video output. Example register settings for other features and the VBI data processor are not provided here.

4.1Example 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, PAL-M, and PAL-60 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 2 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.

4.2

Example 2

4.2.1

Assumptions

Input connector:

S-video [VI_2_C (luma), VI_1_C (chroma)]

Video format:

NTSC (J, M, 443), PAL (B, D, G, H, I, N, Nc, 60) or SECAM (default)

Output format:

10-bit ITU-R BT.656 with discrete sync outputs

4.2.2 Recommended Settings

Recommended I2C writes: This setup requires additional writes to output the discrete sync 10-bit 4:2:2 data, HS, and VS, and to autoswitch between all video formats mentioned above.
