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
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).
JP17 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 JP1, JP5, JP9, JP13, JP18 2-3 Pull down to GND to enable output (OE#0, OE#4, OE#8, OE#12, OE#16) with pin control option.
JP2, JP3, JP4, JP6, JP7, JP8, JP10, JP11, JP11, J12, JP14, JP15, JP16, JP19, JP20, JP21 - Not populated on the EVM. If additional outputs are needed, then these jumpers need to be soldered onto the EVM, as well as the respective output edge SMA connectors.
SMBus Address Control Pins JP25, JP26 - Refer to Table 3-6 or selecting SMBus address.
Digital Pins JP23, JP24 1-2 TCA Reset and CLKPWRGD_PD# pulled high.
JP22 1-3 SBEN pin = GND
J49 - SN74LVC125 buffer enable control pin. Default pull down to GND.
