2 EVM Quick Start

The default jumper configuration for the EVM to power the device from an onboard 3.3V LDO with USB supply option is shown in Table 2-1. Configure the EVM for initial bring up as specified in Table 2-1. The EVM can also be configured to external power supply by changing the position of jumper JP17 as described in Table 2-1.

Table 2-1 Default Jumper Configuration
CategoryReference DesignatorDefault PositionDescription
PowerVDD_A1-2Connect USB or external supply to VDDA of device.
VDD1-2Connect USB or external supply to output bank and digital supply of the chip (VDD).
VDD_IO1-2Connect USB or external supply to IO pins on board (VDD_IO).
JP31-2Choose between USB power supply and external. Current configuration is for external supply. To change to USB power, change jumper position to 2-3.
Output Enable Control PinsOE0#, OE#1, OE#2, OE#3, OE#4, OE#5, OE#6, OE#7, OE#8, OE#9, OE#10, OE11#2-3Pull down to GND to enable output (OE#0-11) with pin control option.
SMBus Address Control PinsSADR0, SADR1-Refer to Table 3-6 or selecting SMBus address.
Digital PinsTCA_Reset, CKPWRGD_PD#1-2TCA Reset and CLKPWRGD_PD# pulled high.
SBEN2-33-pin header. To enable SBI, change jumper position to 1-2 (connect to VDD).
SBEN-SN74LVC125 buffer enable control pin (2-pin header). Default pull down to GND.
