• Manufacturer Part Number: bcm1104
• Description: Bcm1104 - Gigabit Ip Phone Chip
• Manufacturer: Broadcom Corp.

The Broadcom BCM1104 IP phone chip enables manufacturers to build
IP phones with hardware security and best-in-class voice quality.
The chip also integrates a Gigabit Ethernet (10/100/1000 Mbps) switch
and two Fast Ethernet (10/100 Mbps) transceivers, allowing for the
optional 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 BCM1104 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, thereby
providing assurance that the identity of each phone in the network is
genuine.
The chip's high-performance RISC processor 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
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.
