5G MIMO Radio: RF & Timing

Higher bandwidth requirements for cellular services have increased the global demand for 5G multiple-input multiple-output (MIMO) solutions. This system implements the RF chains and clock tree necessary for 5G MIMO.

System Benefits​:

• Eliminates the need for separate synchronizers and VCXO-based jitter attenuators to meet PN targets, addressing reference clock needs for RF LO, RF sampled ADC/DAC, and SerDes up to 224Gbps.
• Reduces BOM cost and overall system area by supporting synchronization to PTP and SyncE with RF clock generation in a single device.
• Enhances thermal reliability and simplifies PCB layout.
• Supports multiple synchronization modes, including SyncE, Enhanced SyncE, PTP, and GPS/GNSS.
