Output Signals; Jumper Settings - Analog Devices AD9266 Quick Start User Manual

jumper J605 Pin 2 to J605 Pin 3 to disable the oscillator and remove C610 to disconnect the on-board
crystal oscillator.

Output Signals

The default setup uses the Analog Devices high speed converter evaluation platform (
HSC-ADC-EVALCZ) for data capture. The outputs from the ADC are routed to Connector P902. For
more information on the data capture board and its optional settings, visit
www.analog.com/hsadcevalboard.

Jumper Settings

Set the jumper settings/link options on the evaluation board for the required operating modes before
powering on the board. The functions of the jumpers are described in Table 1. Figure 2 shows the
default jumper settings.
Table 1. Jumper Settings
Jumper Description
In the default state, the MODE_OR pin is an output that indicates an overrange condition.
Connecting Pin 1 to Pin 2 connects the MODE_OR pin to an on-board LED to give a visual
indication of overrange. SPI writes to Register 0x08 and Register 0x2A can configure the
J203
MODE_OR pin to be an input that controls power-down and standby modes. In the case
where MODE_OR is configured as an input, connecting Pin 2 to Pin 3 invokes the
programmed pin function; see the product datasheet for more information.
J302 sets the ADC for SPI communications with the HSC-ADC-EVALCZ.
J302
Connect Pin 1 to Pin 2 for SDIO, Pin 4 to Pin 5 for SCLK, and Pin 8 to Pin 9 for CSB.
This jumper enables or disables the on-board crystal oscillator. Jumper Pin 1 to Pin 2 to
J605 enable the crystal oscillator; Jumper Pin 2 to Pin 3 to disable the oscillator, in the case
where an external off-board clock source is used.
These jumpers select between internal V
To choose the internal (on-chip) 1 V reference, connect J201 Pin 2 (DUT_SENSE) to J201
Pin 3 (GND). No jumpers are needed on J202 for the internal (on-chip) 1 V reference.
To use the on-board

1 (1.8V_DUT_AVDD), and connect J202 Pin 2 (DUT_VREF) to J202 Pin 3 (EXT_REF).
J202
To apply a reference voltage from an external off-board source, connect J201 Pin 2
(DUT_SENSE) to J201 Pin 1 (1.8V_DUT_AVDD) and apply the reference voltage to J202 Pin
2 (DUT_VREF). The reference voltage is specified at 1.0 V for the AD9266, AD9649,
AD9629, and AD9609.
