Product Details

The HMC7044 is a high performance, dual-loop, integer-N jitter attenuator capable of performing reference selection and generation of ultralow phase noise frequencies for high speed data converters with either parallel or serial (JESD204B type) interfaces. The HMC7044 features two integer mode PLLs and overlapping on-chip VCOs that are SPI-selectable with wide tuning ranges around 2.5 GHz and 3 GHz, respectively. The device is designed to meet the requirements of GSM and LTE base station designs, and offers a wide range of clock management and distribution features to simplify baseband and radio card clock tree designs. The HMC7044 provides 14 low noise and configurable outputs to offer flexibility in interfacing with many different components including data converters, field-programmable gate arrays (FPGAs), and mixer local oscillators (LOs).

The DCLK and SYSREF clock outputs of the HMC7044 can be configured to support signaling standards, such as CML, LVDS, LVPECL, and LVCMOS, and different bias settings to offset varying board insertion losses.

View Detailed Evaluation Kit Information

The HMC7044 meets the requirements of multi-carrier GSM and LTE base-station designs and offers a wide range of clock management and distribution features to simplify baseband and radio card clock tree designs. The high performance dual-loop core of the HMC7044 enables the base station designer to attenuate the incoming jitter of a primary system reference clock, such as a CPRI source, with the help of the narrow-band configured first PLL loop, which disciplines an external VCXO, and generate the low phase noise, high frequency clocks with the wider-band second PLL to drive data converter sample clock inputs.

The EK1HMC7044LP10B evaluation board is a compact, easy-to-use platform for evaluating all the features of the HMC7044. A 122.88 MHz VCXO is mounted on the evaluation board to provide a complete solution. All inputs and outputs are configured as differential on the evaluation board.

AD-SYNCHRONA14-EBZ

View Detailed Evaluation Kit Information

The AD-SYNCHRONA14-EBZ is an ideal self-contained device to use in evaluation and prototyping of applications that need a highly accurate frequency and phase-controlled source clock. It is designed around the Analog Devices AD9545 and HMC7044 and greatly simplifies clock distribution and multi-channel synchronization in complex systems. It is intended to be used by trained professionals in a laboratory environment, and not intended as an end product for commercial use. It can be taken as a complete reference design and customised as required for any end customer applications. Full design details are made available free of charge.

The AD-SYNCHRONA14-EBZ comes in a 1U mechanical form factor. Using popular industry connector SMA and TwinAX interfaces most labs will already have the needed cables.

With its internal OCXO it can operate in standalone mode or be fed from a choice of external sources, such as 3 separate high speed differential clock inputs, a 10MHz reference and 1PPS. This flexibility combined with the capability to select either of the internal VCXO options of 100MHz or 122.88MHz, gives almost unlimited choice for the frequency of interest and accuracy needed for a wide variety of application areas.

QUAD-MxFE Platform

View Detailed Evaluation Kit Information

The Quad-MxFE System Development Platform contains four MxFE® software defined, direct RF sampling transceivers, as well as associated RF front-ends, clocking, and power circuitry. The target application is phased array radars, electronic warfare, and ground-based SATCOM, specifically a 16 transmit/16 receive channel direct sampling phased array at L/S/C band (0.1 GHz to ~5GHz). The Rx & Tx RF front-end has drop-in configurations that allow for customized frequency ranges, depending on the user’s application.

The Quad-MxFE System Development Platform highlights a complete system solution. It is intended as a testbed for demonstrating multi-chip synchronization as well as the implementation of system level calibrations, beamforming algorithms, and other signal processing algorithms. The system is designed to mate with a VCU118 Evaluation Board from Xilinx®, which features the Virtex® UltraScale+™ XCVU9P FPGA, with provided reference software, HDL code, and MATLAB system-level interfacing.

In addition to the Quad-MxFE Digitizing Card, the kit also contains a 16Tx / 16Rx Calibration Board that is used to develop system-level calibration algorithms, or otherwise more easily demonstrate power-up phase determinism in situations pertinent to their own use case. The Calibration Board also allows the user to demonstrate combined-channel dynamic range, spurious, and phase noise improvements and can also be controlled via a free MATLAB add-on when connected to the PMOD interface of the VCU118.

The system can be used to enable quick time-to-market development programs for applications like:

ADEF (Phased-Array, RADAR, EW, SATCOM)
Communications Infrastructure (Multiband 5G and mmWave 5G)
Electronic Test and Measurement
