Key modules integrated in the BCM1113 include: • MIPS32 87.5-MHz processor with 8K 2-way set associative I-cache and a 4K 2-way associative D-cache. This MCU supports the VoIP protocol stacks, jitter buffer management, and application program. Programming is done in C, on top of Broadcom’s object-oriented signal processing API. • ZSP 108-MHz DSP with 48-KB instruction and 32-KB data RAM. The DSP supports a wide range of vocoders, acoustic echo cancellation for full-duplex speakerphone, fax modems, and a variety of telephony algorithms (e.g., DTMF and Call Progress Tones). • Analog codecs. Three ADCs and DACs are integrated, eliminating the need for an analog switch to allow the sharing of a codec between multiple interfaces. 64 KB of Buffer Memory DMA Arbiter • 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 BCM1113 integrates all the key silicon components of an Ethernet IP Phone into a single device and is pin and software compatible with the BCM1101. The BCM1113 is suited for SOHO Voice-over IP phone products that require mid-range application feature sets (e.g., basic user applications operating on 2-line character displays) while still requiring the same voice quality and reliability of higher end IP phone products.
