4.1.1.1 CPRI Master
(Ask a Question)When the CPRI master is configured, it receives IQ data, Vendor specific data, Antenna carrier control data, and Ethernet data from the respective pattern generator blocks. It then frames incoming data into the CPRI frame format at the rate of 4.9152 Gbps and transmits it to the serial lines through the XCVR interface.
On the receive side, the CPRI master receives the data from the serial lines through the XCVR interface in the CPRI frame format, it then unpacks the data and sends the received IQ, VSS, and Ethernet data to the respective pattern checker block.
