  • Page 2 Introduction The Texas Instruments DS90UB925QSEVB evaluation kit (EVB) provides an easy way to evaluate the operation and performance of the DS90UB925Q 2.975Gbps FPD-Link III serializer. 1.1. Contents of DS90UB925QSEVB 1- DS90UB925Q EVB, 1- CD with ALP software, 1- USB cable 1.2.
  • Page 3 www.ti.com 1.3. Operation – Quick Setup Make sure S1, S2, S3, S4, and JP2 are configured as shown in Figure 1. 1) Turn on the deserializer. Typically this would be the DS90UB926Q EVB. 2) If interfacing to 3.3V LVCMOS, skip this step, otherwise: when interfacing to 1.8V LVCMOS inputs (upstream device), move factory jumper from pin-2/3 to pin 1 to connect to pin-1/2 and apply 1.8V power to pin 1 of JP1.
  • Page 4: Power Connections

    The PDB switch is set HIGH and will turn on the DS90UB925Q upon power up. SW2 is a momentary switch. Instead of toggling switch 1 of S1 to do a PDB toggle, press SW2 to do a PDB toggle. DS90UB925QSEVB User’s Guide Sept 2012...
  • Page 5 www.ti.com 2) The S2 and S3 switches are factory set as shown below. All switches are set HIGH except 18 on S3. This sets IDx address to 18. Note only one switch is allowed LOW at a time. 3) The S4 switch is factory set as shown below. All switches are set HIGH except 1.
