2.1 EVM Quick Start

Table 3-1 describes the default jumper configuration of the EVM to power the device from an on-board 3.3-V LDO with USB supply option. Configure the EVM as specified in Table 3-1 for initial bring up. The EVM can also be configured to use an external power supply by changing the position of jumper JP12 as described in Table 3-1.

Table 2-1 Default Jumper Configuration
Category Reference Designator Default Position Description
Power J5 1-2 Connect USB or external supply to VDDA of device.
J6 1-2 Connect USB or external supply to output bank and digital supply of the chip (VDD).
J7 1-2 Connect USB or external supply to IO pins on board (VDD_IO).
JP12 2-3 Choose between USB power supply and external. Current configuration is for USB option. To change to external supply, change jumper position to 1-2.
Output enable control pins JP10, JP15 2-3 Pull down to GND to enable output (OE#0, OE#4) with pin control option.
JP7, JP8, JP9, JP11, J13, JP14 - Not populated on the EVM. If additional outputs are needed, these jumpers need to be soldered onto the EVM as well as their respective output edge SMA headers.
SMBus address control pins JP3, JP4 - Refer to Table 3-8 for selecting SMBus address.
Digital pins JP1, JP2 1-2 TCA Reset and CLKPWRGD_PD# pulled high.
JP5 1-3 SBEN pin = GND.
J2 - SN74LVC125 buffer enable control pin. Default pull down to GND.
JP6 2-3 Slew Rate SEL Pin pulled Low by default.
