Synchronous multi-transformer circuit design based on DAC3XJ8X

To further expand the range of modern mobile communication systems and increase their data rate and reliability, the system designer can continue to put more focus on multi-antenna transmitter system to achieve spatial diversity and space multiplexing. These implementations can further compensate for path loss and multi-path effects of the transmission medium. These implementations may also expand the range and increase data rate and reliability. Multi-antenna systems using beamforming techniques also help to better centralize transmitter energy, and the system may reduce the antenna size while expanding the transmitter range. More mobile communication systems and radar systems begin to use multi-antenna transmitters in their design. For these multi-antenna transmitters, each transmitter needs to use a digital-to-analog converter (DAC) to perform RF transmission to the numeric bit. It is also necessary to synchronize multiple transmitters and their associated antennas. This design uses JESD204B subclass 1 type DAC3XJ8X, which enables multiple DAC3XJ8X devices to synchronize. DAC3XJ8X is a high speed 16-bit DAC whose sample rate is as high as 2.8 GSPS. All functions of DAC3XJ8X simplifies the design of the device to synchronize and facilitate multi-antenna transmitter system. Characteristic High speed data transmission High sampling rate JESD204B subclass 1 support Multi-device synchronization Synchronous clock allocation
