PRODUCT OVERVIEW

The PM7830 Baseband to Radio Interface Controller (BRIC) is a fullfeatured 6-port termination device that fully supports the CPRI specification for wireless base station interconnection. The BRIC provides integrated rate-adaptive SERDES links along with CPRI framing, mapping, switching, and combining functions.

When used in conjunction with the 2-port PM7832 BRIC-2, the BRIC and BRIC-2 can be used to flexibly create scalable CPRI-compliant distributed architectures.

PRODUCT HIGHLIGHTS

• Operates in all of the following Baseband-to-RF interconnect topologies:

• Local interconnect using a central combiner/distributor topology.

• Local interconnect using a full mesh topology.

• Remote interconnect using a point-to-point (P2P) star topology.

• Remote interconnect using a tree and branch topology.

• Remote interconnect using a chain topology.

• Remote interconnect using a ring topology.

• 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. • Supports multiplexing and termination of control and synchronization sub-channels:

• Up to 6 Ethernet Fast C&M channels.

• Up to 6 HDLC Slow C&M 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.

• Supports configuration, control, monitoring and test capability on a per-channel basis.
