FEATURES

SUMMARY OF BENEFITS

• The BCM1113 is the most highly integrated silicon solution

targeted for midrange Voice-over IP enterprise phones

• The BCM1113 integrates:

• 87.5-MHz MIPS32™ CPU (96 DMIPS) with 8K I-cache and

4K D-cache

• Superscalar 108-MHz ZSP DSP with dual-MAC (216 MIPS),

48K instruction, and 32K data RAM

• Three-port 10/100BASE-T Ethernet switch with 64K buffer

memory

• Two 10/100BASE-T Ethernet PHYs with in-line power over

Ethernet support

• Three wideband audio ADCs and DACs

• 9 x 9 keyscan controller

• Ethernet status LED driver

• TDM IOM-2® port

• Two UARTs

• Two high-speed serial ports

• General purpose I/O

• Interrupt control unit

• DMA support unit

• SDRAM interface

• External bus interface

• IEEE 1149.1 (JTAG)

• 0.18µ process technology, 1.8/3.3V

• 1.1W peak, 0.3W – 0.8W standby modes

• 256-pin PBGA package enables 4-layer PCB designs

• Pin and software compatible with the BCM1101, BCM1113R,

BCM1115, and BCM1115R ICs

• 10/100BASE-T Ethernet Switch with 802.1p/Q support

• 802.1p priority queuing ensures QoS for voice packets and

minimizes latency

• Supports modification of 802.1p priority tags on packets to

enforce priority tagging rules

• 802.1Q VLAN support allows for segmenting physical

networks into multiple logical networks

• MIPS32 CPU not burdened by data packet processing, leaving

more cycles for application program

• Enables wire-speed non-blocking operation

• Blocks unnecessary traffic by learning local MAC addresses

• Segments network, preventing any restriction on number of

hops

• 87.5-MHz MIPS32 CPU and 108-MHz DSP Support

• VxWorks Operating System

• SIP, H.323, H.248/Megaco, and MGCP

• G.711, G.726, G.729A/AB/E, G.723.1/A, G.728, G.722.1 and

BroadVoice®

• Full-duplex speakerphone operation

• Handset echo suppression

• Two- and three-channel conferencing using complex vocoders

• Enhanced Packet Loss Concealment

• Paging (via a G.711 channel)

• User application software

• 10/100BASE-T Ethernet MACs and PHYs

• Integrates support for Cisco in-line power specification

• Compliant with 802.3af power over Ethernet standard

• Provides auto-MDI/MDIX, enabling the use of straight or

crossover cables in either port

• Wideband audio CODECs

• Enables support of emerging wideband vocoding standards

HARDWARE PLATFORMS
