Preliminary Technical Data
EVALUATION BOARD DESCRIPTION
The AD9261 is a 16-bit analog-to-digital converter (ADC)
featuring a high performance and wideband continuous time
sigma-delta (Σ-Δ) modulator followed by decimation filters and
a sample rate converter. An on-chip PLL based clock multiplier
and voltage reference are available for ease of implementation
and optimal performance. Figure 1 shows the functional block
diagram of the AD9261.
The AD9261 evaluation platform offers flexibility in evaluating
and characterizing the performance of the ADC. The evaluation
board provides two options to drive the inputs of the ADC: a
differential amplifier (AD4937-1) and a transformer path. The

on-board ADR130B provides an accurate and stable band-gap
voltage for an optional external reference, and the AD9516-0
provides the ADC with many clocking options.
Complementing the AD9261 evaluation board are additional
hardware and software to capture and process the digital data
from the output of the ADC. The AD9261 can only be
evaluated using the HSC-ADC-EVALCZ high speed ADC data
capture card in conjunction with the VisualAnalog
capture and analysis software. The SPIController
used to read and write to the AD9261.

... The default configuration of the AD9261 evaluation board allows a quick and easy start to evaluating the ADC. The default configuration uses a transformer to drive the single-ended to differential inputs of the AD9261 and an external 640MHz for the clock input. Table 1 and Figure 4 show the hardware required to start the evaluation. ...
