PICTURE

The OP5355 and OP5356 differential output family feature 32 output channels organized into two banks of 16 channels each.


Description

Users have the choice of three output options:

  • The OP5356-3 provides a 3-volt RS-422 output
  • The OP5356-5 provides a 5-volt RS-422 output
  • The OP5355 provides an LVDS output.

The OP5355 and OP5356 differential output family feature 32 output channels organized into two banks of 16 channels each. The output signals are galvanically isolated, providing electrical isolation between the simulator and the output signals. Thus, both the simulator and the end devices are protected from surges and short circuits.

All outputs provide differential signals, meaning that longer cables can be used to feed the end devices. In a long cable, stray electromagnetic fields in the environment, or stray currents in the system ground, can induce unwanted noise voltage that may cause errors at the receiver. By using a differential output signal, both signals receive the same amount of interference, so by subtracting the positive signal by its complementary signal, the original data can be recovered at the receiver, eliminating all electromagnetic noise that may have affected the signal in the transmission line.

Features

  • Card features 32 output channels organized into two banks of 16 channels each
  • Each channel has a differential output signal
  • The simulator is galvanically isolated from the output signals
  • The module operates at very high speed
  • The schematic below shows the signal being fed from the FPGA side to the level shifter, through the galvanic isolation, then through an RS-422 or LVDS driver, and then finally to the user's terminal.
