PM7830 BRIC
Baseband Radio Interface Controller
Advance Product Brief 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.
* 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

APPLICATIONS
Two of the many possible architectural implementations using the BRIC and BRIC-2 are shown below:
* Central combiner-based CPRI architecture where the BRIC is used as
channels across all links.
* 16-bit microprocessor interface compatible with both Intel-like and
Freescale-like processors.
BENEFITS
* Provides all necessary functions for implementing CPRI-based
a termination and switching device for the interconnect of BRIC-2based REC and RE CPRI endpoints.
* Chain-based CPRI architecture where the BRIC is used to terminate
Chain, Ring, Point-to-Point architectures, and more.
* Hitless protection switching, IQ summing, AxC switching & multicast
