For customers designing Analog devices RF Agile Transceiver “AD936x”
EPSON TCXO matching trial for Analog Devices RF Agile Transceiver AD936x Comparison with Analog Devices specifications and measurement data.
The measurement data almost matched the specifications. As conclusion, TCXO (TG5032CAN) is suitable for AD936x reference clock.
|TCXO frequency for reference clock|
|TCXO phase noise||N.A.||N.A.||Matching|
|TX LOintegratedphase noise||800MHz(700MHz to 900MHz)||Matching||Almost Matching||N.A.|
|2.4GHz(1.8GHz to 2.7GHz)||N.A.||N.A.||Almost Matching|

Analog Devices AD936x
Analog Devices AD936x RF Agile Transceivers are high performance and highly integrated one that is designed for small cell and base station application. - AD936xRF frequency : 800MHz, 2.4GHz, and 5.5GHz
Reference clock recommendation for Analog Devices AD936x
We recommend TCXO TG5032CAN for AD936x reference clock as follows.
10MHz to 50MHz
EPSON tested AD9361 Reference Board (AD-FMCOMMS3-EBZ) with our TCXO TG5032CAN as external reference clock, and measured TCXO phase noise and TX LO integrated phase noise, and confirmed whether the noise matches AD9361 data sheet at 800MHz and 2.4GHz.
Phase Noise data is as follows: - TG5032CAN 40MHz without Filter - TG5032CAN 40MHz with Filter - ADI Expected spec for 40MHz
Conclusion: TG5032CAN 40MHz with Filter is qualified by ADI data sheet.
◆ LO=700MHz to 900MHz, TCXO frequency=19.2MHz
Conclusion: Our measurement result is qualified by ADI spec sheet.
◆ LO=700MHz to 900MHz, TCXO frequency=30.72MHz
Conclusion: Our measurement result is almost qualified by ADI spec sheet. The difference is only 0.01 mdeg RMS. at 800MHz.
◆ LO=1.8GHz to 2.7GHz, TCXO frequency=40MHz
Conclusion: Our measurement result is almost qualified by ADI spec sheet. The difference is only 0.05 mdeg RMS. at 2.4GHz Our result fluctuates slightly up and down, but the trend of characteristics matches.
