Product Details

The AD9523 and AD9524 are designed to operate in the same manner.

The AD9523 is defined to support the clock requirements for long-term evolution (LTE) and multicarrier GSM base station designs. It relies on an external VCXO to provide the reference jitter cleanup to achieve the restrictive phase noise requirements necessary for acceptable data converter SNR performance. 

The input receivers, oscillator, and zero delay receiver provide both single-ended and differential operation. When connected to a 30.72 MHz to 122.88 MHz reference clock and a VCXO of either 30.72 MHz to 122.88 MHz, the device generates low noise outputs from a range of 0.96 MHz to 983.04 MHz.


Evaluation Software

4.39 M
AD9523/AD9524 Evaluation Software Installer (Rev. 2.1.3)
This installer contains USB drivers that are both 32- and 64-bit compatible. Note: Older AD9523/AD9524 evaluation boards will need to have the USB controller EEPROM re-flashed in order to use this driver.
1.22 K
AD9523/AD9524 Evaluation Board USB Flash Programmer Readme
EVB flash readme: This file contains instructions for re-flashing the USB controller on an older eval board so that the evaluation board is compatible with the newer 64-bit USB driver. The USB driver is also 32-bit compatible.
7.35 M
Evaluation Board USB Flash Programmer
Contains the EXE file for re-flashing the USB EEPROM.
