EVM Quick Start

Table 3-1 describes the default jumper configuration of the EVM to power the device from an external power supply. Configure the EVM as specified in Table 3-1 for initial bring up. The EVM can also be configured to use an on-board 3.3V LDO with USB supply option by changing the position of jumper JP9 as described in Table 3-1.

Table 2-1 Default Jumper Configuration
Category Reference Designator Default Position Description
Power J14 1-2 Connect USB or external supply to VDD_IN0 of device.
J15 1-2 Connect USB or external supply to output bank and digital supply of the chip (VDD).
J16 1-2 Connect USB or external supply to VDD_IN1 of device.
J17 1-2 Connect USB or external supply to VDD_BANK0 of device.
J18 1-2 Connect USB or external supply to VDD_BANK1 of device.
J20 1-2 Connect USB or external supply to IO pins on board (VDD_IO).
JP9 1-2 Choose between USB or external power supply. Current configuration is for external power. To change to USB power, change jumper position to 2-3.
Output enable control pins JP5 through JP8 2-3 Pull down to GND to enable output (OE#0 through OE#3) with pin control option.
Digital pins JP1 1-2 CLKPWRGD_PD# pulled high.
JP2 2-3 ZOUT_SEL pulled low setting output impedance to 85Ω.
JP3 2-3 SMB_EN pin pulled low disabling SMBus.
JP4 2-3 CLKIN_SEL_tri pulled low to set CLKIN0 as the input source to all the outputs.
