My board has 3 pairs of differential signals and 1 pairs of clocks going to another board through a cable.
- The cable should be at least 20cm.
- The data rate is 1G from a xilinx FPGA (LVDS_25)
I am looking for an affordable connector for this board-to-cable connection. Any suggestion?
As with any protocol, max speed depends on distance and modulation type for compression with equalization and/or pre-compensation. It will not be simple NRZ or bi-phase data.
Impedance control may require SMD 1GHz Baluns to raise CMRR immunity from conducted CM SMPS noise between subsystems and shielding to lower impedance to 50 ohms single-ended or 100 Ohms differential.
