ENTERPRISE IP PHONE CHIP
FEATURES
SUMMARY OF BENEFITS
•
The BCM1113 is the most highly integrated silicon solution
targeted for midrange Voice-over IP enterprise phones
•

•
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

IEEE 1149.1 (JTAG)
•
0.18µ process technology, 1.8/3.3V
•
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
•

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
