See Input Termination for proper input terminations, dependent on single-ended or differential inputs.
See LVDS Output Termination for output termination schemes depending on the receiver application.
TI recommends unused outputs to be terminated differentially with a 100-Ω resistor for optimum performance, although unterminated outputs are also okay but will result in slight degradation in performance (Output AC common-mode VOS ) in the outputs being used.
In this example, the PHY, ASIC, and FPGA or CPU require different schemes. Power-supply filtering and bypassing is critical for low-noise applications.
See Power Supply Recommendations for recommended filtering techniques. A reference layout is provided in Low-Additive Jitter, Four LVDS Outputs Clock Buffer Evaluation Board (SCAU043).
