The AD9546 Evaluation Board is a compact, easy-to-use platform for evaluating all features of the AD9546 multiple input, 10-Output, Dual Channel, Numeric Clock Synchronizer. The AD9546 supports existing and emerging International Telecommunications Union (ITU) standards for the delivery of frequency, phase, and time of day over service provider packet networks, including ITU-G.8262, ITU-T G.812, ITU-T G.813, ITU-T G.823, ITU-T G.824, ITU-T G.825, and ITU-T G.8273.2.

The 10 clock outputs of the AD9546 are synchronized to any one of up to four input references. The digital phase-locked loops (DPLLs) reduce timing jitter associated with the external references. The digitally controlled loop and holdover circuitry continuously generate a low jitter output signal, even when all reference inputs fail. The AD9546 system clock is provided by a 52 MHz crystal. Alternatively, an external clock signal may be provided at a SMA connector (relative components must be populated to enable this functionality).

Applications

• 5G timing transport high precision synchronization
• Global positioning system (GPS), PTP (IEEE 1588), and synchronous Ethernet (SyncE) jitter cleanup and synchronization
• Optical transport networks (OTN), synchronous digital hierarchy (SDH), and macro and small cell base stations
• Small base station clocking (baseband and radio)
• Stratum 2, Stratum 3e, and Stratum 3 holdover, jitter cleanup, and phase transient control
• JESD204B support for analog-to-digital converter (ADC) and digital-to-analog converter (DAC) clocking
• Carrier Ethernet

The EVAL-AD5676RARDZ allows users to quickly prototype AD5676R circuits and reduce design time. The AD5676R operates from a single 2.7 V to 5.5 V supply. The AD5676R incorporates an internal 2.5 V reference to give a full-scale output voltage of 2.5 V or 5 V. An ADR4525 is also provided on-board as a 2.5V reference source. A different external reference voltage can be applied via the EXT_REF SMB connector or test pin if needed.

The EVAL-AD5676RARDZ interfaces to the USB port of a PC via a system demonstration platform board (SDP-K1 ). The Analysis | Control | Evaluation (ACE) software is available for download from the EVAL-AD5676RARDZ product page to use with the evaluation board to allow the user to program the AD5676R. A peripheral module interface (PMOD) connection is also available to allow the connection of microcontrollers to the evaluation board without the SDP-K1 board. When a microcontroller is used through the PMOD connection, the SDP-K1 board must be disconnected, and the user is unable to operate the ACE software.

The EVAL-AD5676RARDZ is compatible with the EVAL-SDP-CK1Z (SDP-K1), which should be purchased separately. A typical connection between the EVAL-AD5676RARDZ and the SDP-B controller board is shown in the user guide. For full details, see the AD5676R data sheet, which must be used in conjunction with the user guide when using the EVAL-AD5676RARDZ.

The ADM7160 evaluation boards demonstrate the operation and functionality of the ADM7160 ultralow noise, 200 mA, linear regulator.

Simple device measurements such as line and load regulation, dropout voltage, and ground current can be demonstrated with only a single voltage supply, load resistors, and a voltmeter or an ammeter.

Complete specifications for the ADM7160 ultralow noise, 200 mA, linear regulator are available in the ADM7160 data sheet available from Analog Devices, Inc., and should be consulted in conjunction with this user guide when using the evaluation boards.

The AD-JUPITER-EBZ is a versatile software-defined platform based on Analog Devices ADRV9002 and Xilinx Zynq UltraScale+ MPSoC. The ADRV9002 is a new generation RF transceiver that has dual-channel transmitters, dual-channel receivers covering a frequency range of 30 MHz to 6 GHz. This device has a high-quality RF linearity performance and a set of advanced features like fast profiles switching, flexible power vs. performance configuration, fast frequency hopping, multi-chip synchronization, and digital pre-distortion (DPD) for narrow and wide band waveform.

The evaluation platform includes XCZU3EG processing device that has a wide range of interfaces, making the system capable of local processing or streaming to a remote host. It comes integrated in a self-contained ruggedized aluminum case, which gives flexibility in evaluating and prototyping across different environments.
