الوصف العام
- This user guide describes the hardware and software of the HMC7044B evaluation kit. The evaluation board schematic and printed circuit board (PCB) layout artwork can be found on the EK1HMC7044BLP10B product page at www.analog.com.
- The HMC7044B meets the requirements of multicarrier GSM and LTE base station designs, and offers a wide range of clock management and distribution features that simplify baseband and radio card clock tree designs. The high performance dual-loop core of the HMC7044B enables the base station designer to attenuate the incoming jitter of a primary system reference clock, such as a CPRI source, using the narrow-band configured first phase-locked loop (PLL), which disciplines an external voltage-controlled crystal oscillator (VCXO), and to generate the low phase noise, high frequency clocks with the wider-band second PLL to drive data converter sample clock inputs.
- The EK1HMC7044BLP10B evaluation board is a compact, easy-to-use platform for evaluating all the features of the HMC7044B. A 122.88MHz VCXO is mounted on the evaluation board to provide a complete solution. All inputs and outputs are configured as differential on the evaluation board. Full specifications on the HMC7044B are available in the product data sheet, which must be consulted in conjunction with this user guide when using the evaluation board.

ابدء
SOFTWARE INSTALLATION PROCEDURES To install the ACE software and HMC7044B plugin, perform the following steps:
- قم بتثبيت أحدث إصدار من النظام الأساسي لبرنامج ACE.
- If the HMC7044B plugin appears automatically, proceed to Step 4.
- Double click the HMC7044B plugin file,
Board.HMC7044_SDP.1.2023.47100.acezip. - Check that the HMC7044B plugin appears when the EK1HMC7044BLP10B board is attached to the PC through the system demonstration platform (SDP) connector.
إجراءات إعداد مجلس التقييم
The EK1HMC7044BLP10B board uses a single 6V power supply with VCC_IN and AGND banana plugs by default. On-board low-noise, low-dropout (LDO) regulators generate nominal 3.3V and 5V supplies.
Details of the power supply circuitry are given in the Power Sup-plies section.
To power up the board, perform the following steps:
- اضبط مجلد مصدر الطاقةtage as 6V and the current limit as 2A.
- Connect power cables to VCC_IN and AGND (two banana cables).
- قم بتشغيل الطاقة.
لتشغيل البرنامج، قم بالخطوات التالية:
- حدد ابدأ > كافة البرامج > الأجهزة التناظرية > ACE.
- On the Select Device and Connection tab, choose HMC7044B and the HMC7044B board appears under attached hardware.
- When connecting the EK1HMC7044BLP10B board, allow 5 sec to 10 sec for the label on the status bar to change.
جهاز مجلس التقييم
- The EK1HMC7044BLP10B requires the SDP-K1 platform that uses the EVAL-SDP-CK1Z.
- The EK1HMC7044BLP10B schematic and artwork are shown in Figure 9 to Figure 20.
إمدادات الطاقة
- The EK1HMC7044BLP10B board is powered by a 6V power supply connected to the banana plug, VCC_IN, and GND to the banana plug, AGND.
- The power supply circuitry has an LT8622S/LT8624S, step-down silent switcher 3 with ultra-low noise reference.
- One LT8622S is used to generate all the supplies for the HMC7044B, except VCC_VCO. The LT3045, low-noise, LDO regulator on board, provides a clean supply to the on-board 122.88MHz VCXO and internal VCO of the HMC7044B.
SETTING UP THE SIGNAL CONNECTIONS
After setting up the power and PC connections, use the following procedure to set up signal connections:
- Connect a signal generator to the CLKIN0_RFSYNC_P SMA Connector J11. By default, the reference inputs on the evaluation board are AC-coupled. Terminate the CLKIN0_RFSYNC_N SMA Connector J10 with a 50Ω termination. An amplitude setting of 6dBm from the signal generator is sufficient.
- Connect an oscilloscope, spectrum analyzer, or other lab equipment to any output of the CLKOUTx_P or CLKOUTx_N SMA connectors. Place a 50Ω termination on all unused differential output pairs.
BYPASSING THE 6V SUPPLY AND THE LT8622S
The evaluation board contains one on-board S, step-down silent switcher 3 with ultra-low noise reference, and two LTC3045 devices, LDO regulators to regulate the 6V to 3.3V supply domain. The evaluation board can be configured to bypass the silent switcher and the LDOs, which is useful for increasing the HMC7044B power consumption efficiency. The evaluation board schematics are provided in the Evaluation Board Schematics and Artwork section. Bypass the 6V silent switcher for the HMC7044B as follows:
- Remove the on-board LT8622S (U2).
- Remove R8 and L1.
- Remove R100 and R101.
- Install R360 and R364.
Connect a bench 3.3V power supply to each of the supply pins on the 3.3V main header (TP15). Note that it is very important to not have the 6V supply connected to the TP15 of the evaluation board.

برنامج لوحة التقييم
The ACE software is the main platform that is used to control the EK1HMC7044BLP10B. The HMC7044 plugin includes user interfaces that relate to the HMC7044B and allow evaluation of the device. Use the following steps to open the main control window for the HMC7044B:
- Launch the ACE application. With the SDP-K1 board connected to the EK1HMC7044BLP10B, the attached hardware appears in the graphical user interface (GUI) as shown in Figure 3.
- Double click the HMC7044 Board icon and the tab shown in Figure 4 appears.
- Double click the HMC7044 icon that appears on the board GUI to open the main control window shown in Figure 5.
الضوابط الرئيسية
The main controls are available in the high-level register map shown in Figure 5. To modify registers, perform the following steps:
- ACE plugin is opened with preconfigured register values for jitter cleaner application. Click Apply Changes to upload suggested register settings for initialization.
- Modify the registers as required.
- Click Apply Changes to load modified settings to the device. This action loads the updated registers only.
- Some of the internal frequencies can be calculated depending on the user input. Therefore, other changes are expected when the user interact with certain fields.
- Restart, Slip, Reseed, Pulsor, and Sleep requests can be triggered by the buttons at the bottom part shown in Figure 5.
- Click Memory Map Side-By-Side and Export to save the specific register configuration. It exports the register values to a CSV file.
