• Manufacturer Part Number: bcm1113r
• Description: Bcm1113r - Ip Phone Chip
• Manufacturer: Broadcom Corp.

Broadcom's BCM1113R is a highly integrated IP phone chip specifically
targeted at the cost-sensitive consumer equipment market.
Key modules integrated in the BCM1113R include:
• MIPS32 87.5 MHz processor with 8K 2-way set associative I-cache
• ZSP 87-MHz DSP with 48-KB instruction and 32-KB data RAM.
• Analog codecs: integrated analog CODECs capable of supporting

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.
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.
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

transceivers. The three-port Ethernet switch integrates three full-
duplex 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 twisted-
pair 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.
