Dialog Semiconductor VoIP technology adopted by VTech for S-series desktop phones

The first of which, the S-series of single and dual-line phone systems, has been designed for the hotel market and went into mass production in the fourth quarter of 2011. The design win successfully extends Dialog’s relationship with VTech, which is already using the company’s DECT IC technology in its digital cordless phones.



VTech’s S-series VoIP phones incorporate multi-call and multi-handset capabilities, speakerphone functionality, IEEE802.3af power over Ethernet, and a USB charging facility, together with an array of other advanced hotel phone features. Furthermore, the VTech SIP cordless desktop phones incorporate DECT, CAT-iq and DECT 6.0 with an adjustable coverage area to deliver improved clarity and installation management.



C.H. Tong, President of VTech Telecommunications Ltd, commented: “Communications are increasingly done over IP, and our goal is to exceed user expectations with our VoIP telephony products, providing clear and reliable communications solutions. Our S-series phones have been designed first and foremost with audio clarity and ease of use at their heart and Dialog’s VoIP chips and software are the key to achieving this.”



Jalal Bagherli, CEO of Dialog, added: “VTech is among the world’s leading brand names, especially in the phone market, and is already a customer for our DECT digital cordless phone ICs. Our close working cooperation has helped us extend our relationship with this second product line and integrate our Green VoIP processors into VTech’s latest designs.”



The Dialog SC14452 is an award-winning VoIP IC with built-in DECT support and has the flexibility to meet the diverse needs of users and manufacturers. It features a 16-bit CompactRISC™ processor and two user-programmable Gen2DSPs to deliver 240-MIPS of computational power. The device uses a low clock frequency to achieve the industry’s lowest power consumption figures, saving as much as 2W per desktop phone compared with other solutions. It integrates a 32KHz wideband audio codec, Class D amplifier and PAEC (Perfect Acoustic Echo Canceller) to deliver exceptional audio clarity. Its sister device, the SC14461, has all the capabilities of the SC14452 but without DECT support and is aimed at corded desktop models.
