| NBSG111BAEVB Evaluation Board Manual for NBSG111 http://onsemi.com EVALUATION BOARD MANUAL DESCRIPTION This document describes the NBSG111 evaluation board and the appropriate lab test setups. It should be used in conjunction with the NBSG111 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 NBSG111 GigaCommTM 1:10 clock data driver. The NBSG111 allows selection between two inputs and fan out 10 identical differential outputs. The Reduced Swing ECL (RSECL) output ensures minimal noise and fast switching edges. 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 W impedance from the scope to be used as termination of the ECL signals (VTT = VCC - 2.0 V, in split power supply setup, VTT is the system ground). What measurements can you expect to make? With this evaluation board, the following measurements could be performed in single-ended(1) or differential modes of operation: * Jitter * Output Skew * Gain/Return Loss * Eye Pattern Generation * Frequency Performance * Output Rise and Fall Time * VIHCMR (Input High Common Mode Range) 1. Single-ended measurements can only be made at VCC - VEE = 3.3 V using this board setup. Figure 1.

Power Supply Connections 3.3 V Setup VCC = 2.0 V VTT = GND VEE = -1.3 V 2.5 V Setup VCC = 2.0 V VTT = GND VEE = -0.5 V Connect Inputs Step 2: For Differential Mode (3.3 V and 2.5 V operation) 2a: Connect the differential output of the generator to the differential input of the device (CLK0 and CLK0). For Single-Ended Mode (3.3 V operation only) 2a: Connect the AC coupled single-ended output generator to input. NOTE: For best results, unconnected input should be terminated to VTT through 50 W resistor VCC VCC = 2.0 V Channel 1 Channel 2 Float VTT = 0 V Signal Generator VCC CLK0 OUT Q0 OUT Amplitude = 500 mV Offset = 660 mV Q9 CLK0 VEE EN EN GND Q9 VTT = 0 V VCC Float SEL SEL GND Q0 Channel 3 Channel 4 Digital Oscilloscope Channel 5 Channel 6 Channel 7 Channel 8 TRIGGER * Q0 - Q9 Ouputs TRIGGER VEE = -1.3 V (3.3 V op) -or- VEE = -0.5 V (2.5 V op) NOTE: All differential cable pairs must be matched.

NBSG111 Board Setup - Time Domain (Differential Mode) http://onsemi.com 2 NBSG111BAEVB Setup (continued) Setup Input Signals Step 3: 3a: Set the signal generator amplitude to 500 mV. NOTE: The signal generator amplitude can vary from 75 mV to 900 mV to produce a 400 mV DUT output. 3b: Set the signal generator offset to 660 mV (the center of a nominal RSECL PECL output). NOTE: The VIHCMR (Input High Voltage Common Mode Range) allows the signal generator offset to vary as long as VIH is within the VIHCMR range. Refer to the device data sheet for further information. 3c: Set the generator output for a PRBS data signal, or for a square wave clock signal with a 50% duty cycle. Connect Output Signals Step 4: 4a: Connect the outputs of the device (Q0, Q1, ...) to the Oscilloscope. The oscilloscope sampling head must have internal 50 W termination to ground. NOTE: Where a single output is being used, the unconnected output for the pair must be terminated to VTT through a 50 W resistor for best operation. Unused pairs may be left unconnected. Since VTT = 0 V, a standard 50 W SMA termination is recommended.
