| NBSG86ABAEVB Evaluation Board Manual for NBSG86A http://onsemi.com EVALUATION BOARD MANUAL DESCRIPTION This document describes the NBSG86A evaluation board and the appropriate lab test setups. It 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 GigaCommTM 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 NBSG86A is used to program the peak-to-peak output amplitude between 0 and 800 mV in five discrete steps. The board is implemented in two layers and provides a high bandwidth 50 W 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 NBSG86A 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 is required enabling the 50 W impedance from the scope to be used as termination of the ECL signals, where VTT is the system ground (VCC = 2.0 V, VTT = VCC - 2.0 V and VEE is -0.5 V or -1.3 V, see Setup 1). What measurements can you expect to make? The following measurements can be performed in the single-ended (Note 1) or differential mode of operation: * Frequency Performance * Output Amplitude (VOH /VOL) * Output Rise and Fall Time * Output Skew * Eye pattern generation * Jitter * VIHCMR (Input High Common Mode Range) NOTE: 1. Single- ended meas urements can only be made at VCC - VEE = 3.3 V using this board setup. Figure 1.

For Single-Ended Mode (3.3 V operation only) 2a: Connect an AC-coupled output of the generator to the desired differential input of the device. 2b: Connect the unused differential input of the device to VTT (GND) through a 50 W resistor. 2c: Connect the DO input to VTT. 2d: Connect the DO input to VCC. 2e: Connect the generator trigger to the oscilloscope trigger. All Function Setups Connect OLS (Output Level Select) to the required voltage to obtain desired output amplitude. Refer to the NBSG86A device data sheet page 2 OLS voltage table. Setup Input Signal Step 3: 3a: Set the signal generator amplitude to 400 mV. Note that 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 output). Note that 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 square wave clock signal with a 50% duty cycle, or for a PRBS data signal. Connect Output Signals Step 4: 4a: Connect the outputs of the evaluation board (Q, Q) 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. http://onsemi.com 3 NBSG86ABAEVB OR/NOR Function Setup V = 2.0 V VTT = 0 V VTT = 0 V CC VCC = 2.0 V Oscilloscope GND Signal Generator Amplitude = 400 mV Offset = 660 mV OUT SEL Q Channel 1 D1 D1 VCC OUT SEL OUT1 OLS D0 OUT1 OLS* TRIGGER *See NBSG86A data sheet pg 2.
