BCM1103

Description

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 BCM1103 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 chip's high-performance RISC processor and DSP support 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® codec, a 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 BCM1103 IP phone designs. The RISC processor further allows customers to add product-differentiating application software.
