(1) When the device is configured to receive data over a 10-bit interface, the ITU-R.BT656 output bus on the THS8200 can be enabled via
an I²C register bit to send the received data to an external device. In other DMAN modes, this output should remain off (data_tristate656
register).
(2) SMPTE293M-compliant
(3) Dedicated timing not supported with 10-bit interface.
(4) ITU-R.BT656-compliant
(5) Because PC graphics data is normally only 8 bits wide, only 3×8 bits (8 MSBs of each bus) are used. Color space converter bypass is
required for modes with pixel clock > 150 MSPS.
Table 4-1 summarizes all supported video mode configurations.
Each video mode is characterized by three attributes:
• Input Interface: Data is accepted over 10-, 20- or 30-bit interface (or 8- ,16-, 24-bit interface for 8-bit
data when using 8 MSBs of each input data bus and connecting 2 LSBs to ground). This selection is
controlled by the dman_cntl register.
• Timing control: Video timing is either embedded in the data stream or supplied via dedicated timing
signals. In the latter case additional Hsync (HS_IN), Vsync (VS_IN) and FieldID (FID) input signals are
required to synchronize the video data source and THS8200 in the case of slave timing mode. This
selection is controlled by the dtg2_embedded_timing register.
• Synchronization: Video timing either is supplied to the device (slave) or the THS8200 requests video
data from the source (master). This selection is controlled by the chip_ms register.
NOTE
Device operation with combinations of settings for the dman_cntl, dtg2_embedded_timing
and chip_ms registers that result in operating modes not marked in Table 4-1 is not
assured. See detailed register map description for actual register settings.
