7.2 Register Descriptions

Between { } are shown the name(s), subaddress(es) and bit position(s) where each register can be found in the register map.

The default register value is shown between [ ] in binary format, and hexadecimal (h) and/or decimal (d) notation where listed.

7.2.1 System Control (Sub-Addresses 0x02−0x03)

ver(7:0): Device version
{version 0x02(7..0)} [0000 0000]
The user can read this register to find out which version of THS8200 is in the system.
vesa_clk: Clock mode selection
{chip_ctl 0x03(7)} [0]
0 : Normal operation
1 : All clocks become identical, except for the half-rate clock, and the DLL is bypassed. This is used in VESA mode to support a direct 205-MHz input clock. No internal 2x interpolation is available. This mode should be used for all formats that require a >80 MSPS pixel clock because the internal DLL for 2x clock generation is specified only up to 80 MSPS.
The half-rate clock is still internally generated if needed to allow, for example, 148-MHz 20-bit input (1080P).
dll_bypass: DLL bypass
{chip_ctl 0x03(6)} [0]
0 : DLL used for clock generation; normal operation with internally generated 2x clock. This mode should be selected for most video formats when a 1x clock is available on the device clock input, and either 1x or 2x DAC operation is desired internally (as selected by register data_ifir35_bypass)
1 : DLL bypassed for clock generation. In this case the clock input on the CLKIN pin is used directly as the 2x clock, rather than the internally generated signal from the DLL.
vesa_colorbars: Color bar test pattern
{chip_ctl 0x03(5)} [0]
0 : normal operation
1 : Device generates color bar pattern; external video inputs are ignored. The color bar pattern is only supported in VESA PC graphics mode, with the device configured in master mode
(chip_ms = 1).
dll_freq_sel: dll_freq_sel:
{chip_ctl 0x03(4)} [0]
Sets a frequency range for the DLL 2x clock generation. The DLL should not be used at >80 MHz. In this case the vesa_clk register should be enabled. As a consequence, 2x video interpolation is not available for formats with >80 MHz pixel clock.
0 : high frequency range: pixel clock from 40−80 MHz
1 : low frequency range: pixel clock from 10−40 MHz
dac_pwdn: dac_pwdn:
{chip_ctl 0x03(3)} [0]
0 : normal operation
1 : DACs go into power-down state.
chip_pwdn: Chip power down
{chip_ctl 0x03(2)} [0]
0 : normal operation
1 : power down of all digital logic except I2C
chip_ms: Chip mode select
{chip_ctl 0x03(1)} [0]
0 : slave mode. Device synchronizes to incoming video sync signals, either embedded in ITU-R.BT656 interface or received from dedicated timing signals.
1 : master mode. Device requests video data and generates video input timing signals to external (memory) device, according to the programmed frame/field format. Master mode is only available when the DTG is operating in VESA mode (PC graphics signals).
arst_func_n: Chip software reset
{chip_ctl 0x03(0)} [1]
0 : functional block goes into reset state. I2C registers retain values.
Note: the user needs to issue a software reset after input video is disconnected from the input bus and reconnected (for example after a video format change), to synchronize the internal display timing generator to the input video source properly.
1 : normal operation

dtg2_fid_de_cntl: FID (field-ID)/DE (data enable)input selection for FID terminal
{dtg2_cntl 0x82(7)} [0]
Controls interpretation of signal on FID terminal
0 : Signal interpeted as FieldID
1 : If the DTG is programmed to the VESA mode, the FID pin becomes a data-enable input pin. Data enable is assumed high during the active video window, and low outside this area. This is compatible with the DE signal from TI DVI receivers. Data is passed through the THS8200 only when data enable is high. Otherwise, the input data is overridden by the THS8200 internally programmed blanking value. If the DTG is programmed in the SDTV or HDTV video mode with dedicated timing signals, a 1 in this register location causes the THS8200 to generate an internal FieldID value from the relative alignment of Hsync and Vsync inputs, rather than using the signal on the FID input pin (which is ignored). This is for EIA-861 compliant operation for video-over-DVI 1.0 (with HDCP) where there is no dedicated FID signal available but the even/odd field ID is determined from Hsync/Vsync alignment.
dtg2_rgb_mode_on: RGB/YPbPr mode selection
