PANGKALAHATANG PAGLALARAWAN

• 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.
• Natutugunan ng HMC7044B ang mga kinakailangan ng mga disenyo ng multicarrier na GSM at LTE base station, at nag-aalok ng malawak na hanay ng pamamahala ng orasan at mga tampok sa pamamahagi na nagpapasimple sa mga disenyo ng puno ng orasan ng baseband at radio card. Ang mataas na pagganap na dual-loop core ng HMC7044B ay nagbibigay-daan sa base station designer na bawasan ang papasok na jitter ng isang pangunahing system reference clock, gaya ng CPRI source, gamit ang narrow-band configured first phase-locked loop (PLL), na nagdidisiplina ng external vol.tage-controlled crystal oscillator (VCXO), at upang makabuo ng mababang bahagi ng ingay, mga orasan na may mataas na dalas na may mas malawak na banda na pangalawang PLL upang himukin ang data converter sampang mga input ng orasan.
• 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.

PAGSIMULA

SOFTWARE INSTALLATION PROCEDURES To install the ACE software and HMC7044B plugin, perform the following steps:

1. I-install ang pinakabagong bersyon ng ACE software platform.
2. If the HMC7044B plugin appears automatically, proceed to Step 4.
3. Double click the HMC7044B plugin file,
   Board.HMC7044_SDP.1.2023.47100.acezip.
4. Check that the HMC7044B plugin appears when the EK1HMC7044BLP10B board is attached to the PC through the system demonstration platform (SDP) connector.

MGA PAMAMARAAN SA PAG-SETUP NG EVALUATION BOARD
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:

1.  Itakda ang power supply voltage as 6V and the current limit as 2A.
2. Connect power cables to VCC_IN and AGND (two banana cables).
3. I-on ang power.

Upang patakbuhin ang software, gawin ang mga sumusunod na hakbang:

1. Piliin ang Start > All Programs > Analog Devices > ACE.
2.  On the Select Device and Connection tab, choose HMC7044B and the HMC7044B board appears under attached hardware.
3. When connecting the EK1HMC7044BLP10B board, allow 5 sec to 10 sec for the label on the status bar to change.

HARDWARE NG EVALUATION BOARD

• Ang EK1HMC7044BLP10B ay nangangailangan ng SDP-K1 platform na gumagamit ng EVAL-SDP-CK1Z.
• Ang EK1HMC7044BLP10B schematic at artwork ay ipinapakita sa Figure 9 hanggang Figure 20.

MGA KAPANGYARIHAN

• Ang EK1HMC7044BLP10B board ay pinapagana ng isang 6V power supply na konektado sa banana plug, VCC_IN, at GND sa banana plug, AGND.
• Ang circuitry ng power supply ay may LT8622S/LT8624S, step-down na silent switcher 3 na may napakababang sanggunian sa ingay.
• Ang isang LT8622S ay ginagamit upang bumuo ng lahat ng mga supply para sa HMC7044B, maliban sa VCC_VCO. Ang LT3045, low-noise, LDO regulator na nakasakay, ay nagbibigay ng malinis na supply sa on-board na 122.88MHz VCXO at panloob na VCO ng HMC7044B.

I-SET UP ANG MGA SIGNAL CONNECTION
Pagkatapos i-set up ang power at PC connections, gamitin ang sumusunod na procedure para mag-set up ng signal connections:

1. 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 ampsapat na ang setting ng litude na 6dBm mula sa generator ng signal.
2.  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.

PAGBIBIGSA SA 6V SUPPLY AT SA LT8622S
Naglalaman ang evaluation board ng isang on-board S, step-down na silent switcher 3 na may napakababang sanggunian ng ingay, at dalawang LTC3045 na device, LDO regulators para i-regulate ang 6V hanggang 3.3V supply domain. Maaaring i-configure ang evaluation board upang i-bypass ang silent switcher at ang mga LDO, na kapaki-pakinabang para sa pagtaas ng kahusayan sa paggamit ng kuryente ng HMC7044B. Ang evaluation board schematics ay ibinibigay sa Evaluation Board Schematics at Artwork na seksyon. I-bypass ang 6V silent switcher para sa HMC7044B tulad ng sumusunod:

1. Remove the on-board LT8622S (U2).
2. Remove R8 and L1.
3. Remove R100 and R101.
4. Install R360 and R364.

Ikonekta ang isang bench na 3.3V power supply sa bawat isa sa mga supply pin sa 3.3V main header (TP15). Tandaan na napakahalaga na hindi konektado ang 6V supply sa TP15 ng evaluation board.

3. Double click the HMC7044 icon that appears on the board GUI to open the main control window shown in Figure 5.

PANGUNAHING KONTROL
The main controls are available in the high-level register map shown in Figure 5. To modify registers, perform the following steps:

1. ACE plugin is opened with preconfigured register values for jitter cleaner application. Click Apply Changes to upload suggested register settings for initialization.
2.  Modify the registers as required.
3.  Click Apply Changes to load modified settings to the device. This action loads the updated registers only.
4. 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.
5.  Restart, Slip, Reseed, Pulsor, and Sleep requests can be triggered by the buttons at the bottom part shown in Figure 5.
6. Click Memory Map Side-By-Side and Export to save the specific register configuration. It exports the register values to a CSV file.
