Conexant Launches IP "Phone-on-a-Chip"

Conexant Systems announced the first in a family of integrated VoIP phone solutions. Conexant's single-chip CX90600 system solution, which targets IP and Web-based desktop phone terminals for business and residential applications, is based on the ARM926EJ core and includes a set of peripheral interfaces that enable connectivity to smart cards, flash drives, video cameras and 802.11 a/g wireless LANs. Integrated interfaces include a three-port Ethernet switch to enable local and wide area network connections, a universal serial bus (USB) 2.0 controller, a high-performance peripheral component interconnect (PCI) 2.3 interface, a high-speed universal asynchronous receive/transmitter (UART), a keypad interface, a FXO interface, a FlexIO interface, and several general purpose I/Os.


Additional features include support for a wide variety of low bit rate and wideband speech coding schemes including G.711, G.722, G.726 and G.729ab, as well as dual-tone multi-frequency (DTMF) and dial tone detection/generation telephony algorithms without the need for an external digital signal processing (DSP) device. The chip also provides acoustic echo cancellation capability for high-quality voice transmissions and full-duplex speakerphone.


In addition, the CX90600 features an integrated memory management unit (MMU), a high-resolution liquid crystal display (LCD) controller, caches, tightly coupled memory (TCM), and an analog codec allowing for a single-chip IP phone design.


The device is priced at $15.00 in quantities of 10,000. http://www.conexant.com
