Green VoIP processor addresses high end phones

Dialog Semiconductor plc has announced a high performance VoIP phone chipset, the SC14453. The single chip processor enters the companyís VoIP portfolio as its flagship product and integrates hardware blocks for best-in-class audio, security and graphics functionality.

The SC14453 has been created for mid and high end desktop phones and extends the company’s portfolio - alongside the SC14452 and SC14461 - of award winning Green VoIP ICs, which now contains devices to support entry level through to high end designs.

The on-board multicore VoIP processor delivers 590 MIPS of computational power with industry-leading power consumption figures, and integrates stereo analogue codecs and a stereo Class D amplifier with 48 kHz support, which along with Dialog’s acoustic echo cancellation and active noise reduction, combine to give best-in-class audio quality for crystal clear voice conversation.

The SC14453’s advanced audio DSPs and its symmetric/asymmetric cryptography accelerator can manage 8 simultaneous SRTP-secured IP calls, and its powerful graphic engine and LCD controller enable the output of fluid graphic user interfaces onto SVGA (800 x 600) touchscreen LCD displays. Dialog’s unique SafeKey feature based on Intrinsic-ID’s security IP block ensures bank-level security authentication of files and software. The SC14453 Green VoIP platform provides a high level of flexibility for wireless and wired extensions to DECT, CAT-iq, Bluetooth, WiFi, LTE, USB and Gigabit Ethernet.

The SC14453 is based on the highly efficient and ultra low power 32-bit MIPS® M14Kc™ processor, has two user-programmable Gen3DSPs, an OpenVG1.1 graphic processing unit and comes in a 15x15mm, 228-pin LLGA package with standard and secure variants.

To reduce time to market the company offers a complete SC14453 VoIP development kit and the certified Rhea VoIP software platform, based on the popular open source operating system, Linux.
