Single-Chip VoIP Solution Embeds Two SLICs and an Ethernet Switch

The first solution to integrate  two Subscriber Line Interface Circuits (SLICs) and an Ethernet switch in a single chip delivers the highest integration and lowest bill of materials to manufacturers of consumer VoIP adapters and IP phone applications.

Developed by ESS Technology the new ES9701 includes all the processors and peripherals necessary to facilitate the construction of a full-featured VoIP phone application.

ESS Technology chose the Consumer Electronics Show in Las Vegas in January to launch the world’s first solution to integrate two Subscriber Line Interface Circuits (SLICs) and an Ethernet switch in a single chip. Including all the processors and peripherals necessary for full-featured VoIP phone applications.

The ES9701 includes a 32-bit RISC processor for the operating system, control and signalling and a 32-bit DSP for voice codecs such as G.711, G.722, G.726 and G.729A/B.  Two SLICs with three sets of audio DACs and ADCs facilitate connection to phone, fax and handset while the Ethernet switch offers two 10/100 MAC/PHYs for WAN/LAN connections. Other key features of the ES9701 include a LCD display and keypad controller, a SDIO interface for WiFi modules and a AES encryption security module.

To enable quick time-to-market for customer product development, the ES9701 comes with a VoIP phone/adapter reference design complete with voice codecs, Session Initiation Protocol (SIP) protocol stack, all necessary drivers and a software development tool chain.

Samples of the ES9701 in a176-LQFP package can be requested through Ismosys.
