The demand for next-generation Voice over Internet protocol (VoIP) phones, featuring higher performance audio and higher resolution color touch screens, is on the rise. VoIP is fast becoming the de facto standard for business and enterprise communications with some key benefits.
However, many VoIP solutions are power hungry and even push up the carbon footprint of a company. The need for Green VoIP processors that feature low power consumption has subsequently increased.
In an effort to provide a Green VoIP processor chipset designed for high-end phones, Dialog Semiconductor plc – a provider of innovative power management, audio and short range wireless technologies – announced the release of the SC14453, a high performance Green on-board multicore VoIP phone chipset.
According to Dialog, its Green VoIP processors not only deliver excellent performance at lower clock frequencies, but feature lowest power consumption figures and can save as much as 2 W per desktop phone.
Extending the company’s Green VoIP IC family to address high-end phones featuring touchscreen LCD displays, the new single chip processor SC14453 is based on the highly efficient and ultra low power 32-bit MIPS M14Kc processor. It has two user-programmable Gen3DSPs, and an OpenVG1.1 graphic processing unit.
Packaged in a 15x15mm, 228-pin LLGA package, the SC14453 chipset includes advanced audio DSPs and symmetric / asymmetric cryptography accelerator that can manage up to eight SRTP-secured IP calls simultaneously.
In addition, the new on-board multicore VoIP processor incorporates a powerful graphic engine and LCD controller, enabling the output of fluid graphic user interfaces onto SVGA (800x600) touchscreen LCD displays.
Featuring the company’s unique SafeKey feature for bank-level file security, the new SC14453 Green VoIP platform also delivers a high level of flexibility for wireless and wired extensions to DECT, CAT-iq, Bluetooth, WiFi, LTE (News - Alert), USB and Gigabit Ethernet.
According to Dialog, the new SC14453 Green VoIP platform can deliver up to 590MIPS of computational power and integrates stereo analogue codecs and a stereo Class D amplifier with 48kHz support. Along with Dialog’s acoustic echo cancellation and active noise reduction, both collectively provide very high audio quality for crystal clear voice conversation.
The other chip processers available in the company’s Green VoIP IC family are the SC14452 and the SC14461.
The company is offering a complete SC14453 VoIP development kit for faster deployment as well as the certified Rhea VoIP software platform along with the chipset, according to company officials in a press release.
