SOT-22342320200-28-E6

Advanced Rev 1.2

Description:
Model SOT-22342320200-28-E6 is a low phase noise frequency
synthesizer module designed and manufactured for standard test
instrumentation, communication, and Radar systems as a local
oscillator. The module covers a frequency range of 22 to 42 GHzwith an exceptional low harmonics and spurious emissions aswell as superior low phase noise performance. The model isexternally referenced. The output power of the module +20 dBm
with ±1 dB power flatness. The frequency step resolution of themodule is up to 0.4 Hz. The phase noise of the oscillator isdependent on the quality of the reference source. The oscillator
has a built-in voltage regulator to further improve the signalquality and provide over voltage protection. The normal
operating state of the oscillator is external referenced. This module can be directly controlled withdigital signals following SPI communication protocol through Micro-D connector. Eravant offers anevaluation kit including the control board under model number, SOT-EVA-S1, with the GUI (Graphic UserInterface) for initial system set and rapid system development as a separate product.

SPI Communication Port:The device is controlled with a SPI communication port. Digital high level (TTL High) is +3.3 V, and its
effective range is from +2.7 V to +3.6 V; digital low level (TTL Low) is 0 V and its effective range is from 0to +0.6 V. To send control signal to this module, the W/R bit is first sent, followed by register address,and data.

Frequency Synthesizer Module, Low Phase Noise, Ka BandThe synthesized frequency unit is 0.1 Hz before being multiplied by ×4. For instance, when synthesizing afrequency of 40 GHz, the data in bits [63:16] should be 40 GHz divided by 4, which equals 10 GHz.
Considering the 0.1 Hz unit, the value should be 10×109×10 or 1.0×1011. In hexadecimal notation (using 6bytes), it is represented as 00174876E800. The data sent through SPI should be0x02_00174876E800_0000.

Evaluation Kit:
The evaluation kit includes a control board, SOT-EVA-S1, and GUI. The control board is not included inthis product, but it can be ordered separately. The evaluation kit allows the users to easily set up thesystem and control the synthesized frequency of this module manually. The computer display of the GUI
interface is shown below.

Note:••••••All data presented is collected from a sample lot. Actual data may vary unit to unit, slightly.
All testing was performed under +25 °C case temperature.
A well-regulated DC power supply capable of delivering +12 VDC/2.5 A is required. The proper
connection of the power supply to the Micro-D connector is illustrated in the outline drawingabove.
Standard Micro-D9 male to Micro-D9 male cable SOT-CC-M9MM9M-S1 is provided to connect
synthesizer with Evaluation Kit SOT-EVA-S1.
The device is controlled via Personal Computer. A SPI-to-serial adapter is needed between thedevice and PC.
Eravant reserves the right to change the information presented without notice.

Caution:••The device is static sensitive. Always follow ESD rules when working with the device.
Wrong bias or reverse bias on the sensor will damage the device.
