JESD204B multi-device synchronization using LMK0461x

 

JESD204B is getting increasingly popular in communication space adopting the beamforming technology. Multiple Antennas per system are used to have better sensitivity. Each Antenna requires synchronization between them to have precise control of phases during transmission and reception. JESD40B is also getting popular in Medical Imaging, phase array radar applications. The LMK0461x device family is the industry ’s highest performance with lowest power jitter cleaner family with JESD204B support. High-frequency device clock and low frequency SYSREF clocks can be generated with programmable analog and digital delays and SYNC functionality. The device provides possibility to control the SYNC and SYSREF functions by SYNC pin (pin mode) or SPI programming. Each clock output can be used either as a device clock or SYSREF clock
