ON Semiconductor NB7L14MMNEVB Manuals

© Semiconductor Components Industries, LLC, 2012 February, 2012 − Rev. 2 1 Publication Order Number: EVBUM2084/D NB7L14MMNEVB NB7L14M Evaluation Board User's Manual Description This document describes the NB7L14M evaluation board and the appropriate lab test setups. It should be used in conjunction with the NB7L14M data sheet which contains full technical details on the device specifications and operation. The evaluation board is designed to facilitate a quick evaluation of the NB7L14M GigaComm clock/data receiver/driver/translator device. The NB7L14M is designed to support the distribution of clock/data signals at high operating frequencies and produces four equal differential clock/data outputs from a single input clock/data. The Current Mode Logic (CML) output ensures minimal noise and fast switching edges. The evaluation board is implemented in two layers for higher performance. Board Lay−up The board is implemented in two layers and provides a high bandwidth 50  controlled impedance environment for higher performance. The first layer or primary trace layer is 5 mils thick Rogers RO6002 material, which is engineered to have equal electrical length on all signal traces from the NB7L14M device to the sense output. The second layer is 32 mils thick copper ground plane. What measurements can you expect to make? With this evaluation board, the following measurements could be performed in single−ended or differential modes of operation: • Jitter • Gain/Return Loss • Eye Pattern Generation • Frequency Performance • Output Rise and Fall Time • VCMR (Common Mode Range) This Evaluation Board User’s Manual Contains: • Information on NB7L14MMNEVB Evaluation Board • Appropriate Lab Setup • Bill of Materials Figure 1.
