Evaluation Board Manual
for NBSG16 and NBSG16VS

DESCRIPTION

This document describes the NBSG16/16VS evaluation
board and the appropriate lab test setups. It should be used
in conjunction with the NBSG16/16VS data sheets which
contain full technical details on the device specifications and
operation. The same PCB is used to evaluate both devices.

The evaluation board is designed to facilitate a quick
evaluation of the NBSG16/16VS GigaComm Differential
Receiver/Driver. The NBSG16 is designed to function as a
high speed receiver/driver device with a reduced output
swing capability suitable for use in high speed signal
amplification and backplane interface applications. The
Reduced Swing ECL (RSECL) output ensures minimal
noise and fast switching edges. The NBSG16VS has the
option to vary the output amplitude swing (additional
V

modulation pin, labeled VS on evaluation board).

CTRL

The evaluation board is implemented in two layers for
higher performance. For standard lab setup and test, a split
(dual) power supply is required enabling the 50 ohm
impedance in the scope to be used as termination of the ECL
signals (V
is the system ground).

The following considerations played a key role to ensure
this evaluation board achieves high-end microwave

• Optimal SMA connector launch

• Minimal insertion loss and signal dispersion

• Accurate Transmission line matching (50 ohms)

• Distributed effects while bypassing and noise filtering
