Figure 8-9 is a typical configuration for creating an external trigger on oscilliscopes. The user adjusts the trigger level, and a DAC converts this trigger level to a voltage the TLV360x can use as a reference. The input voltage from an oscilloscope channel is then compared to the trigger reference voltage, and the TLV3604, TLV3605, and TLV3607 sends an LVDS signal to a downstream FPGA to begin a capture.
