NBSG86ABAEVB

This document describes the NBSG86ABAEVB evaluation board and the appropriate lab test setups. NBSG86ABAEVB should be used in conjunction with the device data sheet, which includes specifications and a full description of device operation.

The board is used to evaluate the NBSG86A GigaCommE differential Smart Gate multi-function logic gate, which can be configured as an AND/NAND, OR/NOR, XOR/XNOR, or 2:1 MUX. The OLS input of the NBSG86ABAEVB is used to program the peaktopeak output amplitude between 0 and 800 mV in five discrete steps.

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 NBSG86ABAEVB device to the sense output. The second layer is 32 mils thick copper ground plane.For standard lab setup and test, a split (dual) power supply m required enabling the 50 impedance from the scope to e used as termination of the ECL signals, where VTT is the ystem ground (V_CC = 2.0 V, V_TT = V_CC - 2.0 V and V_EE s -0.5 V or -1.3 V, see Setup 1).
