Evaluates: MAX2880 MAX2880 Evaluation Kit Procedure 7) Turn on the DC power supply to power on the EV kit board. 1) Verify that all jumpers are in their default positions, as shown in Figure 2. 8) 2) Connect the 20-pin cable between the INTF-3000 board and the EV kit; verify the pin 1-1 connections, as shown in Figure 2. Run MAX2880.exe to launch the EV kit GUI (Figure 3). In the lower right corner, verify that the USB Online box is green. 9) 3) Connect the USB cable from the PC to the INTF-3000 board. In the EV kit GUI, click on Defaults and then Send All button. In the lower right corner, verify that the PLL Lock indicator is green 4) With its output disabled, set the DC power supply to +6.0V. Connect the DC power supply (with a compliance limit of 150mA) to the banana plugs labeled VSUPPLY and GNDSUPPLY. 5) Connect an RF cable from the VCOOUT SMA connector to a signal analyzer or spectrum analyzer. 6) Visit www.maximintegrated.com, search for MAX2880EVK, and download the latest EK kit software installation file. Run the installation file. Follow the steps below to verify board operation: 10) Use a signal analyzer to verify the performance of the EV kit. Under the default setting, the user should expect to see similar output as the TOC07 plot in the Typical Operating Characteristics section in the MAX2880 IC data sheet. 11) The user can also open two more preload register settings (fractional low-noise mode and fractional low-spur mode) from the Settings - Load menu, then hit the Send All button. 12) To input a new output frequency, update the fVco edit box and then hit Enter on the keyboard.

MAX2880 EV Kit GUI www.maximintegrated.com Maxim Integrated 3 Evaluates: MAX2880 MAX2880 Evaluation Kit Detailed Description of Hardware The MAX2880 EV kit is a complete frequency synthesizer consisting of the MAX2880 PLL, on-board 6000MHz VCO, 50MHz TCXO frequency reference, and 3rd-order passive-loop filter. The EV kit is configured with a narrowband, high-performance 6000MHz VCO to demonstrate the IC performance across the 5840MHz to 6040MHz frequency range. The EV kit input and output interfaces use standard 50 SMA connectors. The board also includes the necessary peripheral components and functions needed to power, monitor, and control the IC, including linear power regulators, LED indicators, and SPI bus. To simplify the test setup, the EV kit is configured to operate from a single 5.5V to 6.5V power supply. The 5.5V to 6.5V input voltage range is governed by the chosen on-board LDOs (U6 and U7) and not by the IC. The EV kit can be reconfigured to bypass the on-board LDOs and run off separate 3V and 5V supplies. The EV kit can be modified to evaluate the IC at operating frequencies ranging from 250MHz up to 12.4GHz using an external VCO. This topic is addressed in a dedicated application note. Contact the factory for details.
