Evaluation Board for AD9523-x Clock Generator

The AD9523-1/PCBZ, from Analog Devices, is an evaluation board for the AD9523-1 device. The AD9523-1 is a low jitter clock generator which provides a low power, multi-output, clock distribution function with low jitter performance, along with an on-chip PLL and VCO with two VCO dividers. The on-chip VCO tunes from 2.94 GHz to 3.1 GHz.

The AD9523-1 evaluation board is a compact, easy-to-use plat-form for evaluating all features of the AD9523-1. A 122.88 MHz VCXO is mounted on the evaluation board to provide a complete solution.
The input receivers are configured as differential but the evaluation board has baluns to provide a single-ended input for easy evaluation using common laboratory single-ended signal sources. Output 8 is connected to an ADCLK905 clock buffer to provide a way to evaluate the buffer. Although the ADCLK905 is a 1-to-1 buffer, the performance is similar to the larger fanout buffer, for example, the 1-to-2 buffer, ADCLK925. Output 1 and Output 9 are configured with baluns to provide a single-ended output to drive most test equipment. Output 0 is configured for differential zero delay operation.

Features of the AD9523-1/PCBZ:
- Simple power connection using USB connection and on-board LDO voltage regulators
- LDOs are easily bypassed for power measurements
- AC-coupled differential SMA connectors
- SMA connectors for 2 reference inputs, 2 PLL status outputs, 1 reference test input and 2 VCXO interface inputs/outputs
- Microsoft Windows®–based evaluation software with simple graphical user interface
- On-board PLL loop filter
-Easy access to digital I/O and diagnostic signals via I/O header
-Status LEDs for diagnostic signals
-USB computer interface
-Software calculator provides flexibility, allowing programming of almost any rational input/output frequency ratio
