NB7L1008MNGEVB NB7L1008MNG Evaluation Board User s Manual Introduction The NB7L1008 is a high performance differential 1:8Clock/Data fanout buffer that operates up to www.onsemi.com 12Gbps/7GHz with a 2.5V or 3.3V power supply. ON Semiconductor has developed a universal QFN32 EVAL BOARD USERS MANUAL evaluation board and configured it for the NB7L1008. This evaluation board was designed to provide a flexible and convenient platform to quickly evaluate, characterize and Layer Stack verify the operation of the NB7L1008. L1 (Rogers) This evaluation board manual contains: Information on the NB7L1008 Evaluation Board High-performance SMA connectors are provided for all Test and Measurement Setup Procedures high-speed input & output signal access. This manual should be used in conjunction with the device Evaluation Board Assembly Instructions datasheet, which contains full technical details on the device The QFN32 evaluation board is designed for specifications and operation. characterizing devices in a 50- laboratory environment using high bandwidth equipment. Board Layout The NB7L1008 Evaluation Board provides a high Output Loading/Termination bandwidth, 50- controlled impedance environment and is implemented in one layer. LVPECL Outputs Table 1.
