BCM1112

VOICE OVER IP CPE ENGINE

F E A T U R E S

S U M M A R Y O F B E N E F I T S

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

•

The BCM1112 is the most highly integrated silicon solution for

Ethernet Residential Gateway and Stand-Alone Media

Terminal Adapter applications.

•

802.1p Ensures QoS for voice packets and minimizes latency

802.1Q VLAN support allows for segmenting physical

networks into multiple logical networks

The BCM1112 Integrates:

•

150-MHz MIPS32 CPU (165 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

Ethernet status LED driver

TDM IOM-2^®port

Two UARTs

Two high-speed serial ports

General purpose I/O

•

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

•

150-MHz MIPS32 CPU and 108 MHz DSP Support

•

In VoIP Gateway applications:

- Full SIP client implementation

- G.711, G.726, G.729A/AB and G.723.1/A

- Fax relay (T.38, V.17, V.29, V27ter)

•

- Two voice channels, or one voice channel and one fax

channel, and a third channel limited to G.711 voice

10/100BASE-T Ethernet MACs and PHYs

•

Integrates support for Modified Link Pulse 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

Interrupt control unit

DMA support unit

SDRAM interface

External Bus Interface

IEEE 1149.1 (JTAG)

•

Wideband Audio CODECs

Enables support of emerging wideband vocoding standards

0.18u process technology, 1.8/3.3V

1.1W peak, 0.3-0.8W standby modes

256-PBGA package enables 4-layer PCB designs

Pin Compatible with BCM1101
