Key modules integrated in the BCM1113R include: * MIPS32TM 87.5 MHz processor with 8K 2-way set associative Icache and 4K 2-way associated D-cache. This MCU supports the VoIP protocol stacks, VxWorks operating system, and customer application software. Programming is done in C, on top of Broadcom's object-oriented signal processing API. * ZSP 87-MHz DSP with 48-KB instruction and 32-KB data RAM. The DSP can support narrowband voice communication using G.711, G.726, G.723.1/A, G.729A, or BroadVoice16, and wideband communications using G.722 or BroadVoice32. Full-duplex speakerphone capability is supported in conjunction with any of these voice compression techniques. The DSP also supports enhanced Packet Loss Concealment, Jitter Buffer, and telephony algorithms. * Analog codecs: integrated analog CODECs capable of supporting both narrowband 8 Kilohertz (KHz) and wideband 16 KHz sampling, which, in conjunction with wideband voice coders, such as Broadcom's BroadVoice32, will enable IP phone networks to deliver high fidelity voice transmission * 10/100BASE-T Ethernet switch, media access controllers, and transceivers. The three-port Ethernet switch integrates three fullduplex capable Media Access Controllers (MACs), a serial management port, an address resolution engine, a non-blocking switch controller, 64K of internal switch memory, 802.1p prioritization for voice packets, 802.1Q VLAN support for segmenting physical networks into multiple logical networks, and a set of Management Information Base (MIB) statistics registers. The two transceivers perform all of the functions for 100BASE-T Ethernet in full- or half-duplex mode over Category (CAT) 5 twistedpair cable and 10BASE-T Ethernet in full- or half-duplex mode over CAT 3, 4, or 5 twisted-pair cable. They support auto-MDI/MDIX detection to allow the use of any cable type in either port. The transceivers also integrate support for in-line powering over Ethernet. The BCM1113R is pin and software compatible with the BCM1101 Enterprise IP Phone chip and is suited for IP Phone products that require basic application features sets, while still requiring the same voice quality and reliability of higher end IP phone products.
