Single-chip CPRI solution enables 3G distributed architectures

The PM7830 BRIC-6 and PM7832 BRIC-2 are full-featured 6-and 2-port termination devices that support the Common Public Radio Interface (CPRI) spec for wireless base station interconnect. Developed by PMC-Sierra, the parts make it possible for OEMs and ODMs to offer all defined Remote Radio Head (RRH) network topologies with a standard digital interconnect for distributed base station systems. The two devices accelerate the adoption of distributed wireless base station architectures, which dramatically reduces capital and operational expenditures for carriers; and support multiple air interfaces, including WCDMA, CDMA2000, TD-SCDMA, and WiMAX over CPRI with a single interface solution.

The BRIC product family reduces customer ASIC/FPGA development cost and qualification by providing a complete, flexible, and high-performance end-to-end interface solution. It eliminates the need for any external jitter attenuation circuitry to recover a clock that fully meets CPRI specification requirements.

Targeting distributed wireless base station architectures, the BRIC's high-level integration of multiple functions into a single device reduces board real estate, BOM size, programmable logic gate count, and qualification cycles.
