4. Applications
1. TX/VCSEL Driver Test:
a. After setting up evaluation board for test connect TX input to PPG thru SMA
AC coupling caps and TX output to load.
b. Load TX driving script and observe output on scope.
c. IMOD amplitude control
d. TX waveform control
i. Adjust crossing percentage of waveform by changing Pulse width
control
ii. Adjust Pre-driver current.
iii. Negative impedance control in TX input
iv. Adjust IMOD peaking height. Please check IMOD Peaking enable
control box to activate.
v. Adjust IMOD compensation. Please check IMOD Compensating
control enable control box to activate.
vi. Adjust IMOD peaking width. Please check IMOD Peaking enable
control box to activate.

4. Temperature Sensor Reading Test
a. Set up evaluation board for test.
b. Run script for Temp Sensor reading.
c. Observe temperature reading in GUI.
5. Run any generic test by setting registers manually. If there is a particular test or
setting you would like to run please contact Ensphere’s applications team as they
can advise as to how to successfully run any test. Other possible tests you may
consider:
a. Receive Power Monitoring
b. Bias current programming
c. Set Alarms for Transmit power monitor, Power supply monitor, Receive
Power monitor, Temperature Monitor, Bias current Monitor
d. Set Warnings for Transmit power monitor, Power supply monitor, Receive
Power monitor, Temperature Monitor, Bias current Monitor
e. Measure bias current monitor voltage
