Configuring the Board Before using the software for testing, configure the evaluation board as follows: Connect the evaluation board to the data capture board, as shown in Figure 1. The AD9266, AD9649, AD9629, and AD9609 are all pin compatible and use the same evaluation board. -
Page 4: Power Supplies
(see the Specifications section in the ADC data sheet). When connecting the analog input source, use of a multipole, narrow-band band-pass filter with 50 Ω terminations is recommended. Analog Devices uses band-pass filters from TTE and K&L Microwave, Inc. Connect the filters directly to the evaluation board. -

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. -

50 Ω terminated and ac-coupled to handle single-ended sinusoidal inputs. The transformer converts the single-ended input to a differential signal that is clipped by CR601 before entering the ADC clock inputs. The AD9266,AD9649,AD9629, and AD9609 ADCs are equipped with an internal 8:1 clock divider to facilitate use with higher frequency clocks. -

Note that the settings in Table 2 and Table 3 apply only when CSB is tied high (J302 Pin 8 has no jumper) at power up. Additional information on the standalone (pin) mode is provided in the AD9266, AD9649, AD9629, and AD9609 data sheets. - Page 9 example). Figure 3.
