The OP5357 and OP5358 modules feature 32 differential input channels compliant with RS-422 or LVDS standard.
Three options are available:
OP5357: LVDS inputs.
OP5358-3: 3V RS-422 inputs
OP5358-5: 5V RS-422 inputs
32 differential input channels organized into two banks of 16 channels each
RS-422 or LVDS compliant, depending on the module selected
The schematic below represents the electrical circuit of one channel: the signal coming for the user's unit-under-test is supplied to the channel inputs. It goes through three stages of conditioning : galvanic isolation, RS-422 or LVDS conditioning, and level-shifting to make it compatible with the simulator's FPGA input lines.
Typical Use Cases
Respecting the RS-422 or LVDS standards, the modules are perfectly suited for long-distance signaling. They have been tested with up to 30 m cables between the simulator and the unit under test.
