Analog to digital converters (ADCs) are widely used in various applications, from data acquisition and signal processing to wireless communication. The EVAL-AD7356EDZ is a board developed by Analog Devices Inc. that enables users to evaluate the performance of the AD7356 low-power antenna switchable dual band receiver. This board is suitable for evaluation and development of wireless products, specifically cellular phones.

The EVAL-AD7356EDZ evaluation board contains a low-power, antenna switchable, dual-band receiver optimized for applications operating in both GSM/EDGE and WCDMA frequency bands. The board contains on-board amplification, a low-noise amplifier (LNA) and a voltage-controlled oscillator (VCO). It is also equipped with a low-noise amplifier and a high-performance, low-noise analog-to-digital converter (ADC). The AD7356 data rates range from 2 Mbps to 4 Mbps.

The board is controlled using the AD7356EDZ-GUI graphical user interface (GUI) for the AD7356 low-power antenna switchable dual band receiver. The GUI enables users to configure and access various features of the board, including the receiver’s antenna switching, gain, output power, frequency range, power-down mode, and other parameters. It also provides graphical display of performance data, such as receiver current drain and bit error rate (BER) performance plots. The GUI is also used to control FTDI’s FT2232H USB port, which is used for programming the receiver registers, setting the oscillator’s input voltage, and performing RF calibration.

In addition, the AD7356EDZ evaluation board contains an integrated USB powered regulator (UBP-OFF) for applications requiring stand-alone operations. This integrated regulator provides regulated power for the board in stand-alone operations without the need for an external power supply. The UBP-OFF also supports power tracking, a power down mode, and cost-effective USB-based programming methods.

The EVAL-AD7356EDZ evaluation board is powered by the Analog Devices AD7356 dual-band receiver. It features a maximum dynamic range of 80 dB, compatible power up-down control and diagnostics, and works with both standard single-ended inputs and differential inputs. The board includes on-board calibration circuitry, a high-performance low-noise ADC, and can be configured with a wide range of gain levels.

The board also features a patented closed-loop power control system, which increases efficiency by providing adjustable output power and line-control accuracy. The AD7356 is also protected from transient events. It features on-chip ESD protection, reverse current protection, and thermal shutdown.

Overall, the EVAL-AD7356EDZ evaluation board from Analog Devices Inc. is an excellent solution for evaluating the performance of the AD7356 low-power antenna switchable dual-band receiver. This board offers high dynamic ranges and an adjustable power output level, enabling users to evaluate the performance of their products in various applications. Additionally, it is equipped with an easy-to-use graphical user interface (GUI), which allows users to configure and access various features of the board. Furthermore, the board features an on-board UBP-OFF integrated usb powered regulator, ideal for stand-alone operations.
