EVALUATION BOARD DESCRIPTION
The AD9262 evaluation board serves two purposes: as an
evaluation platform for the 16-bit dual continuous time sigma
delta ADC and as a direct conversion demonstration platform.
Table 1 lists the product features of all the Analog Devices, Inc.,
components in the demonstrator.
The AD9262 is a dual, 16-bit analog-to-digital converter (ADC)
based on a continuous time sigma-delta (Σ-Δ) architecture that
achieves 86 dB of dynamic range over a 10 MHz real or 20 MHz
complex bandwidth. The integrated features and characteristics
unique to the continuous time Σ-Δ architecture significantly
simplify its use and minimize the need for external components.
This evaluation board supports the AD9262 family of products,
including the AD9262BCPZ-10, AD9262BCPZ-5, and
AD9262BCPZ.
Direct conversion architectures, as shown in Figure 1, use a
single frequency translation step to convert the RF channel
directly to baseband without any intermediate frequency stages.
The frequency translation in this direct conversion demonstrator
is accomplished by the ADL5382, which is a quadrature demod-
ulator. The ADL5382 covers the frequency range between 700
MHz and 2.7 GHz.
The AD9262 has passive inputs, therefore allowing the ADL5382
to directly drive the ADC. The AD9262 does not require a filter
preceding the converter because the continuous time sigma-
delta architecture possesses inherent antialiasing capabilities.
See the last page for an important warning and disclaimers.

Therefore, minimal or no filtering is required between the
demodulator and the ADC. A prototype area for a fourth order
filter is provided in which additional filtering can be tested.
To achieve optimal performance from the AD9262, a low jitter
differential clock is necessary, and the AD9516 family of parts
offers superior clock performance. The AD9516 and a crystal
oscillator footprint are included on the evaluation board. In
addition to providing a clock option to the ADC, outputs from
the AD9516 can be used to drive other external capture devices.
The ADR130B offers the option of using an external 0.5 V band
gap reference voltage for the AD9262. The ADP3339 provides a
quiet and reliable voltage source to each of the ADI components.
In addition to offering system-level evaluation of the direct
conversion architecture, the evaluation board offers the flexibility
of isolating the AD9262 from the surrounding components,
enabling a detailed evaluation of only the AD9262. The ADC
inputs can be disconnected from the ADL5382 and be driven
with an external source. The analog inputs of the AD9262 can
be driven from either a differential transformer or the ADA4937,
which is a very low noise, high linearity differential amplifier.
Complementing the AD9262 evaluation board are additional
hardware and software to capture and process the digital data
from the output of the ADC. The AD9262 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 AD9262.
