Description

The PM7830A-PGI is a full-featured 6-port termination device that acts as a Baseband to Radio Interface Controller (BRIC). It fully supports the CPRI specification for wireless base station interconnection. Along with CPRI framing, mapping, switching, and combining functions, it provides integrated rate-adaptive SERDES links.

Specifications and features

• Operates in various Baseband-to-RF interconnect topologies including local and remote interconnects using different topologies
• Supports up to 6 serial channels running independently at CPRI line rates from 614.4 Mbit/s to 2457.6 Mbit/s with 8B/10B-encoded data
• Supports up to 6 parallel Radio Bus Interfaces (RBIs) for output of user data
• Supports CPRI start-up sequence and link-rate auto-negotiation for both REC and RE operating modes
• Supports traffic switching at the CPRI Antenna Carrier (AxC) level
• Supports IQ summing and multiplexing of control and synchronization sub-channels
• Measures round-trip delay on each CPRI link with an accuracy of ±1 ns
• Provides programmable delay insertion to meet CPRI delay calibration requirements
• Supports serial line protection switching and configuration, control, monitoring, and test capability on a per-channel basis

Application Scenarios

The PM7830A-PGI can be used in wireless base stations for CPRI-compliant distributed architectures. It is suitable for various interconnect topologies, including local and remote configurations.
