VoIP Processors (Chips) for IP Phones



The AC494 IP Phone Toolkit is a combined hardware and software IP Phone reference design based on the AC494 System on Chip (SoC) family. AudioCodes’ AC494 SoC (System on Chip) family provides IP Phone developers and manufacturers with a single chip field-proven complete IP Phone solution, integrated with superior voice quality at a competitive price.

AC494 SoC (System on Chip)
In a single chip, the AC494 combines all IP Phone components; including a MIPS 4KEC CPU, AC49x DSP and a 3-port Ethernet Switch (MACs and PHYs) together with a rich set of peripherals such as internal CODECS and serial ports. The AC494 is based on the VoIPerfectHD™ architecture (High Definition VoIP) support, AudioCodes' underlying, best-of-breed, core media gateway technology for its product line. Utilizing its highly integrated structure and requiring only a minimal number of peripheral devices, time to market is rapid with little risk.

Several silicon derivatives of this family allow cost optimization per application, which includes the following devices: AC494, AC495, AC496 and AC495L.

Device CPU Clock DSP Clock USB Voice CODECs Eth. Ports
AC494 165 Mhz 125 Mhz V 2 2
AC495 125 Mhz 100 Mhz - 2 2
AC495L 87.5 Mhz 87.5 Mhz - 2 2
AC496 165 Mhz 125 Mhz - 2 2

IP Phone Toolkit Hardware Design
The AC494 IP Phone Toolkit hardware reference design includes all the peripherals for a complete high-end IP Phone. The AC494 SOC includes the internal interfaces for LCD Display, a keypad, USB, speaker and handset. Additionally, it has a 3-port E-switch and internal MACs/PHYs.


IP Phone Software Development Kit (sdk)
The AC494 IP Phone Toolkit includes a complete Linux Software Development Kit (SDK) supporting voice and network protocols. The software is available in open source code, comprised of separate modules allowing for maximum customization.

Ready to use IP Phones for developers

The AC494 IP Phone toolkit is also available on ready-to-use IP Phones. This allows OEMs and ODMs to develop their software on an actual IP Phone platform.
