Boss把俺的帖子翻了个遍嘛，呵呵，辛苦辛苦，前几天发帖还没注意规范，现在能改的基本都改正了呀，把扣俺的牛还给俺吧！:D

我也没钱啊，下不了

晕！！！

太贵了，要怎样才能赚钱啊

不知道楼主有没有 OBSAI接口的规范

很想下下来看看，可惜没钱啊

很想下下来看看，可惜没钱啊

不错，谢谢了！

楼主自己翻译的资料啊，谢谢共享！

多谢楼主 ,对着英文版看了半天 实在没头绪.......有中文的,呵呵 太好了

look it look it look it

真不错：）

真不错：）  多谢，，，，，

不错:)谢谢了！

这里面怎么赚钱啊，我刚进来

狂顶！~~~~~~~~~~~~~~~！

没钱啊啊啊怎么办呢，顶

想看,没钱呀
怎么找钱呢

怎么才能看到

先谢谢楼,主共享资料
没有钱,先做个记号.

多谢楼主！

很好的资料，多谢了！

好东西啊，谢谢楼主了

不错啊，我天天都在用这个，就是没看过协议

是啊,我也急需这个,要怎么下得到

太贵了呀,怎样才能下载

pm7830推出BRIC解决方案

PM7830 BRIC
PMC-2051672, Issue 1

All rights reserved. Proprietary and Confidential to PMC-Sierra, Inc. and for its customers’ internal use.
Baseband Radio Interface Controller
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.

INTERFACES
• Line side high-speed serial outputs supporting simultaneous
multiple CPRI line rates using a single reference clock input.
• System side parallel Radio Bus Interface (RBI) supporting parallel
output of either:
• Direct CPRI frame payload.
• Unmapped IQ data to/from CPRI frame payload.
• 6-port RMII/SMII Ethernet interface for accessing Fast C&M
channels.
• Multi-channel HDLC serial interface for accessing Slow C&M
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
Chain, Ring, Point-to-Point architectures, and more.
• Hitless protection switching, IQ summing, AxC switching & multicast
functions enable single-device central switch/combiner
architectures.
• Software -compatible BRIC and BRIC-2 allow complete CPRI solutions
to be realized quickly and expanded as needed.
• Enables application-specific performance monitoring & OAM
functions using in-band Ethernet/HDLC control & management subchannels.
• Applicable for UMTS, CDMA, WiMAX solutions and beyond.
• Industry's most complete and low-risk solution with reuse from
PM8358 QuadPHY 10GX SERDES and PM7831 BRIC-FP CPRI Framer.
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
a termination and switching device for the interconnect of BRIC-2-
based REC and RE CPRI endpoints.
• Chain-based CPRI architecture where the BRIC is used to terminate
one or more chains of remotely-located RE devices.
