GMSL2 Repeater
The design of a repeater board helps equalize the GMSL2 interface to extend the usable range from sensor to controller by using Lattice FPGA or can be used as a Power-over-Coax Injector.
Specification:
- Automotive industry standard FAKRA connectors
- GMSL2 with Power-over-Coax
- Maxim Integrated’s GMSL2 serializer and deserializers
- Lattice CrossLink FPGA
PCB Info:
- 6 layers stack-up
- 382 components
- 220 nets
Challenge:
Because the board uses Power-over-Coax GMSL, we must create a stack-up that can meet the requirements for both impedance control and current carry.
Result:
By working closely with the board manufacturer, we were able to select the optimal stack-up solution that complies with the requirements and lowers the cost.
