  • Page 33: Table 9: Clock Recovery Outputs

    80C10B and 80C25GBE modules with Option CRTP provide differential electrical signal outputs. For clock recovery purposes, route the signals to the input of a compatible, external clock recovery unit, such as the Tektronix CR286A Option HS, using high-quality coaxial cables. Use the outputs as single-ended or differential sources.
