CLK X2 and CLK X1
CLKX2 is the delayed and buffered XTI clock signal. CLKX1 is 1/2 frequency clock signal of CLKX2.
VCLK clock output is generally used as data strobing clock for down stream device with DVALID
register setting as (Reg0x03[5:4]=01 or 10).
ITU-R BT.656
If MODE(Reg0x03[7]) is set to “1” , TW9903 outputs ITU-R BT.656 compatible data on VD[15:8] in 8-bit
output mode and on VD[15:0] in 16-bit output mode. All of control signals, sync signals, and clock
signals have the same timing regardless of MODE bit setting. Only VD[15:8] or VD[15:0] video data
changes. If MODE bit is set to “1”,All data between EAV code and SAV code are filled by 0x80 for CbCr
data and 0x10 for Y data. If MODE is set to “1”, this blanking data and SAV/EAV code are the only
difference from CCIR601 mode(MODE=0). TW9903 doesnt output SAV/EAV code if the line doesn t
have HACTIVE signal. SAV code is generated on 4 CLKX2 clock timing before the leading edge of
HACTIVE. EAV code is generated on 4 CLKX2 clock timing after the trailing edge of HACTIVE. 8-bit
output mode is normally used in ITU-R BT.656 mode. But even if TW9903 is in 16-bit output mode, if
MODE is set to “1”, TW9903 output 4 bytes SAV/EAV code on VD[15:0] pins and the rest of HACTIVE
non active period will be filled by Y 0x10 data and CbCr 0x80 data optionally. The changing timing of F
bit and V bit in forth byte of SAV/EAV code are decided by VDELAY and VACTIVE register setting.
EAV code will change before SAV code changes to maintain the compatibility with ITU-R BT.656
standard. Forth byte of SAV/EAV code is comprised of the following 8 bytes eventually. ITU-R BT.656
sequence is consisted of the following one by (a)-(b)-(c)-(d)-(e)-(f)-(a)-(b)-…… If VIPCFG register bit is
set to “1”, MSB bit 7 of forth byte of SAV/EAV code is changed to “0” for special application.
The output timing is illustrated in Figure 13a,13b. The SAV and EAV sequences are shown in Table 3.
