4-CH AHD2.0 RX and 9-CH Audio Codec

2.10.4. 148.5MHz 2-Ch EX-FHD Data Output Mode

Operated in the 148.5MHz EX-FHD Data Out Mode,

NVP6124 outputs VCLK01, VCLK02,

VCLK03, VCLK04 and VDO1[7:0], VDO2[7:0], VDO3[7:0], VDO4[7:0] in the timing as shown in

Figure 2.17. Two Channel EX-FHD data stream represents 8bit BT.656/1120(like) 4:2:2 format

with 148.5MHz multiplexed.

For VCLK01, VCLK02, VCLK03 and VCLK04, phase adjustment can be made against

VDO1~VDO4 using "Clock Delay Control" Register.

- (VCLK_x_SEL, 0xCC~CF[6:4]=0x6 or 7, Control of Output Clock)

- (VCLK_x_DLY_SEL, 0xCC~CF[3:0]=0x0~F, Control of Phase in Output Clock)

- (CH_OUT_SELx, 0xC8[7:4], 0xC8[3:0], 0xC9[7:4], 0xC9[3:0]=0x11, Control how many multiplexed

channel in a port)
