5 Page TWO CHANNEL ITU-R BT.656 TIME-MULTIPLEXED FORMAT WITH 72MHZ
The TW2960 supports two channels ITU-R BT.656 like time-multiplexed format with 72MHz that is
useful to security application requiring two channel outputs through one channel video port. The
CHMDn register enables the dual ITU-R BT.656 like time-multiplexed format and the MAINCHn/SELCHn
register selects channel output to be multiplexed with its own channel on each VD pins. To de-multiplex
the time-multiplexed data in the back end chip, the channel ID can be inserted in the data stream
using the CHID_MD register. Two kinds of channel ID format can be supported. One is horizontal
blanking code with channel ID and the other is ITU-R BT.656 sync code with channel ID. Figure 3 and
Figure 4 illustrate VDn[7:0]/CLKPO/CLKNO pin timing with 72MHz/36MHz clock output mode.
