    To provide the system with channel information, the THS1207 utilizes an active low SYNC signal. When
    operated in a multichannel configuration, the SYNC signal is active low when data from channel one is available
    to the databus. When operated in single-channel mode (single-ended or differential operation) the SYNC signal
    is disabled.
    Figure 26 shows the timing of the conversion when one analog input channel is selected. The maximum
    throughput rate is 6 MSPS in this mode. There is a certain timing relationship required for the read signal with
    respect to the conversion clock. This can be seen in Figure 26 and in the read and SYNC timing table. A more
    detailed description of the timing is given in the timing section and signal description of the THS1207.

    Figure 26. Conversion Timing in 1-Channel Operation
    Figure 27 shows the conversion timing when 2 analog input channels are selected. The maximum throughput
    rate per channel is 3 MSPS in this mode. The data flow in the bottom of the figure shows in which order the
    converted data is available to the databus. The signal SYNC is active low when data of channel one is available
    to the databus. The data of channel one is followed by the data of channel two before channel one is again
    available and the SYNC signal is active low.
