Chapter 1: KCU105 Evaluation Board Features
SFP/SFP+ Module Connectors
[Figure 1-2, callout 15]
The KCU105 board hosts two small form-factor pluggable (SFP/SFP+) P4 and P5 that accept
SFP or SFP+ modules. The connectors are housed within a single dual SFP cage assembly.
The SFP transmit and receive signal data paths are routed with a differential characteristic
impedance of 100Ω (±10%) with an insertion loss of <4 dB up to 8 GHz.
Figure 1-18 shows SFP/SFP+ module connector circuitry typical of the two
implementations.
