VoIP chip for high-end phones




SC14453 Green VoIP processor includes class-leading integrated audio, security and graphics functions

Kirchheim/Teck, Germany, 26 March 2012 Dialog Semiconductor plc(FWB: DLG), a provider of highly integrated innovative power management, audio and short range wireless technologies, today announced a high performance VoIP phone chipset, the SC14453. The single chip processor enters Dialog’s 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 Dialog’s portfolio – alongside Dialog’s SC14452 and SC14461 – of award winning Green VoIP ICs, which now contains devices to support entry level through to high end designs.

“VoIP is fast becoming the de facto standard for business and enterprise communications,” said Dr. Asmund Tielens, Vice President and General Manager at Dialog. “Business user demands have meant that higher performance audio and higher resolution colour touch screens will be an integral part of next generation VoIP phones. The SC14453, with its best-in-class audio and exceptional graphics capabilities, is perfectly positioned to give our customers a competitive edge.”

The on-board multicore VoIP processor delivers 590MIPS of computational power with industry-leading power consumption figures, and integrates stereo analog codecs and a stereo Class D amplifier with 48kHz 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 (800×600) 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.

Dialog semiconductor is aiming for business phones with its latest VoIP chip.

Called SC14453, it includes integrated audio, security and graphics.

“VoIP is fast becoming the de facto standard for business and enterprise communications,” said Dialog v-p Dr Asmund Tielens. “Business user demands have meant that higher performance audio and higher resolution colour touch screens will be an integral part of next generation VoIP phones.”

A 32-bit MIPS M14Kc processor, two user-programmable Gen3DSPs, and an OpenVG1.1 graphic processing unit deliver 590mips, claims the firm, and there are integrated stereo analogue codecs and a Class-D stereo amplifier with 48kHz support.

Acoustic echo cancellation and active noise reduction are included.

“Audio DSPs and a symmetric-asymmetric cryptography accelerator can manage eight simultaneous SRTP-secured IP calls, and the graphic engine and LCD controller enable output onto SVGA [800×600] touch screen LCDs.”

The chip comes in a 15x15mm, 228-pin LLGA package, with standard and secure variants.

There is a development kit, and Linux-based software to go along with it.
