Product Details

The AD9525 evaluation board is a compact, easy to use platform for evaluating all features of the AD9525. Two versions of the evaluation board are available: one with a prepopulated external VCO and loop filter (AD9525/PCBZ-VCO) and one with no VCO/VCXO and no loop filter (AD9525/PCBZ). The user guide focuses on the AD9525/PCBZ-VCO, which already has a VCO and loop filter on board. The AD9525 provides a low power, multioutput, clock distribution function with low jitter performance, along with an on-chip PLL that can be used with an external VCO or VCXO. The VCO input and eight LVPECL outputs can operate up to a frequency of 3.6 GHz. All outputs share a common divider that can provide a division of 1 to 6. The AD9525 also offers a dedicated output that can be used to provide a programmable signal for resetting or synchronizing a data converter. For more information about the device, see the AD9525 data sheet. The user guide should be used in conjunction with the AD9525 data sheet and the software documentation available at www.analog.com/clocks.

Evaluation Software

3.27 M
AD9525 Evaluation Board Software Installer (Rev.
This installer contains USB drivers that are both 32- and 64-bit compatible. Note: Older AD9525 evaluation boards will need to have the USB controller EEPROM re-flashed in order to use this driver.
7.35 M
Evaluation Board USB Flash Programmer
Contains the EXE file for re-flashing the USB EEPROM.
