• Manufacturer Part Number: bcm1103
• Description: Bcm1103 - Gigabit Ip Phone Chip
• Manufacturer: Broadcom Corp.

The Broadcom BCM1103 IP phone chip enables manufacturers to build
IP phones with integrated gigabit Ethernet switching, improved voice
quality, hardware security, and advanced graphics-driven applications.
The chip integrates a gigabit Ethernet (10/100/1000 Mbps) switch and
two fast Ethernet (10/100 Mbps) transceivers, allowing for the
development of traditional fast Ethernet IP phone designs without the
additional cost of adding external transceivers. With the addition of
external gigabit Ethernet transceivers, manufacturers can easily upgrade
their designs to create gigabit Ethernet IP phone models.
The BCM1103 integrates Broadcom's BroadSAFE security technology,
which performs voice encryption and authentication and elevates the
phone's system security using a unique identifier embedded in each chip
that is virtually impossible to decode, hack, or steal. This provides
assurance that the identity of each phone in the network is genuine.
The chip's high-performance RISC processor and DSP supports
Broadcom's field-proven PhonexChange IP telephony software suite.
PhonexChange includes a wide variety of narrowband and wideband

voice coders, including Broadcom's high-fidelity BroadVoice
high-quality full-duplex speakerphone algorithm, advanced jitter buffer
management and packet loss concealment techniques, and a complete
library of standard telephony algorithms required for IP phone designs.
The RISC processor further allows customers to add product-
differentiating application software.
The chip integrates a variety of IP phone peripherals including
wideband-capable analog codecs (coder/decoder) with integrated
amplifiers, IrDA, USB host, and a touch screen digitizer. It also provides
flexible interfaces for external peripherals and memory types. This high
level of integration reduces the phone's bill of material (BOM) costs and
enables phone vendors to build scalable IP phone solutions using a single
architecture.
