BCM1113R VoIP Ethernet Engine
Broadcom's BCM1113R highly integrated phone chip specifically targeted cost-sensitive consumer equipment market. modules integrated BCM1113R include: MIPS32 87.5 processor with 2-way associative I-cache 2-way associated D-cache. This supports VoIP protocol stacks, VxWorks operating system, customer application software. Programming done Broadcom's object-oriented signal processing API. 87-MHz with 48-KB instruction 32-KB data RAM. support narrowband voice communication using G.711, G.726, G.723.1/A, G.729A, BroadVoice16, wideband communications using G.722 BroadVoice32. Full-duplex speakerphone capability supported conjunction with these voice compression techniques. also supports enhanced Packet Loss Concealment, Jitter Buffer, telephony algorithms. Analog codecs: integrated analog CODECs capable supporting both narrowband Kilohertz (KHz) wideband sampling, which, conjunction with wideband voice coders, such Broadcom's BroadVoice32, will enable phone networks deliver high fidelity voice transmission 10/100BASE-T Ethernet switch, media access controllers, transceivers. three-port Ethernet switch integrates three fullduplex capable Media Access Controllers (MACs), serial management port, address resolution engine, non-blocking switch controller, internal switch memory, 802.1p prioritization voice packets, 802.1Q VLAN support segmenting physical networks into multiple logical networks, Management Information Base (MIB) statistics registers. transceivers perform functions 100BASE-T Ethernet full- half-duplex mode over Category (CAT) twistedpair cable 10BASE-T Ethernet full- half-duplex mode over twisted-pair cable. They support auto-MDI/MDIX detection allow cable type either port. transceivers also integrate support in-line powering over Ethernet. BCM1113R software compatible with BCM1101 Enterprise phone chip suited Phone products that require basic application features sets, while still requiring same voice quality reliability higher phone products.
