GENERAL DESCRIPTION ____________________________________________________________

The ONET8501P-EV evaluation board is designed

for easy quick-test as well as comprehensive

evaluation of the ONET8501P 11.3Gbps rate-

selectable limiting amplifier.

This fully assembled and factory tested evaluation

board allows complete validation of all device

functions.

For optimum performance, the board is equipped

with 50ΩSMA connectors and well-controlled 50Ω

impedance microstrip transmission lines.

In order to account for measurement inaccuracies

caused by inevitable line loss, calibration lines are

provided, consisting of the same type of SMA

connectors and microstrip transmission line layout.

Using the GUI, the bandwidth, output amplitude,

output pre-emphasis, input threshold voltage (slice

level) and the loss of signal assert level can be

adjusted.

CALIBRATION LINE _________________________________________________________________

For optimum performance, the EV board is equipped

with 50ΩSMA connectors and well-controlled 50Ω

impedance microstrip transmission lines in the high-

speed data-signal path. However, inevitable line loss

occurs at high frequencies.

In order to account for the resulting measurement

inaccuracies, calibration lines are provided consisting

of the same type of SMA connectors and microstrip

transmission line layout as used in the high-speed

data-signal path.

The microstrip lines are designed as 50Ωmicrostrip

lines close to the SMA connectors. Close to the chip,

the gap between the two lines of the differential pair

narrows resulting in reduced common mode

matching. The differential line impedance however is

kept constant at 100Ωon the entire board.

The calibration line is intended to be used for S21

and S12 calibration purposes. Furthermore, in the

time domain it helps to determine the impact of the

EV board on signal edge speed as well as

deterministic jitter.

SIGNAL PATH AND CONTROL CIRCUITRY _____________________________________________

The signal path consists of the input port SMA

connectors DIN+ and DIN-, the coupling capacitors

C14 and C19, the 50Ωsingle ended / 100Ω

differential input transmission lines, the ONET8501P,

the 50Ωsingle ended / 100Ωdifferential output

transmission lines, the coupling capacitors C15 and

C20, and the output port SMA connectors DOUT+

and DOUT-.

The ONET8501P uses a two-wire serial interface for

digital control of the bandwidth, output amplitude,

output pre-emphasis, input threshold voltage (slice

level) and the loss of signal assert level.

Predetermined settings for bandwidth and LOS

assert levels can also be selected with the external

rate selection pins (RATE1 and RATE0). For more

information on the use of the two-wire interface,

please refer to the ONET8501P data sheet.

The ONET8501P-EV is set-up for full control and

monitoring through the two-wire interface. Manual

control of such features as external rate selection

and output disable can be done by cutting traces at

the appropriate points and using jumpers.

MEASUREMENT SETUP

Follow this procedure to quickly setup for

measurements. The board is pre-set for open loop

operation.

1. Install the ONET8501_gui_install_v0.7.msi or

higher revision file and follow the

instructions. Use the default directory for the

installation.

2. Attach the interface cable from the USB port

of the computer to the USB port of the

evaluation board. The interface circuitry is

powered through the USB cable.

3. The driver for the USB port will need to be

installed. Follow the instructions for installing

a new driver. The driver is located at

C:\Program Files\Texas Instruments\TI

(ONET8501V-ONET8501P) Eval Board\

Driver. Once a particular USB port has been

configured, this same port must always be

used to control the interface board.

4. All control and monitoring functions are done

through the GUI so no jumpers have been

installed except J14 which is set to select an

external power supply.

5. Connect a differential data input signal

source to the SMA connectors DIN+/DIN–.

Set the data rate up to 11.3Gbps. Set the

amplitude between 5mVp-p differential and

2000mVp-p differential. For small input

signals, attenuators may be required.

6. Connect the output SMA connectors

DOUT+/DOUT– through 50Ωmatched impe-

dance cables to a 50Ωoscilloscope with a

bandwidth of at least 12GHz. Ensure that the

maximum input voltage of the oscilloscope is

not exceeded. Use appropriate attenuators if

needed.

7. Apply a +3.3V supply to the +3.3V banana

jack and the supply ground to the GND

banana jack. The typical current

consumption in default mode will be about

36mA.

8. Run the GUI by clicking the ONET8501 GUI

shortcut icon on the desktop. Choose the

ONET8501P tab. The interface will be as

shown in Figure 4. The USB communication

error indicator and I2C communication

indicator should both be green as shown in

Figure 5. If the I2C indicator is red, then

press the reset button on the interface board.

9. The device will power up in a default state

with an output amplitude of 300mVpp. The

features of the device are controlled through

the corresponding sliders or selection

buttons. To use the input threshold control to

its full range, the DC offset cancellation

should be disabled. Please refer to the data

sheet for the register functionality.

10. Typical eye diagrams at 10.3125Gbps are

shown in Figures 6 and 7.

11. The ONET8501P can also be controlled

through the I2C Diag page by typing in the

HEX values for the appropriate registers and

clicking on the Write Bytes box. The register

values can be read by clicking on the Read

Bytes box.
