8.2 Typical Application

8.2.1 Optical Receiver

The TLV360x can be used in conjunction with a high performance amplifier such as the OPA855 to create an

optical receiver as shown in the Figure 8-5. The photodiode is connected to a bias voltage and is being driven

with a pulsed laser. The OPA855 takes the current conducting through the diode and translates it into a voltage

for a high speed comparator to detect. The TLV360x will then output the proper LVDS signal according to the

8.2.2 Logic Clock Source to LVDS Transceiver

The Figure 8-6 shows a logic clock source being terminated and driven with the TLV360x across a CAT6 Cable

to receive an equivalent LVDS clock signal at the receiver end.

8.2.3 External Trigger Function for Oscilloscopes

Figure 8-7 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 TLV360x sends an

LVDS signal to a downstream FPGA to begin a capture.
