Dialog wins VoIP chipset design-in with VTech

Dialog Semiconductor has announced that its low power VoIP chipset has been adopted by Hong Kong-based cordless and corded phone manufacturer VTech.


Under the terms of the partnership VTech is using Dialog’s SC14452 and SC14461 VoIP processors and Rhea software suite to produce a series of VoIP cordless and corded 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.

VTech already uses the company’s DECT ICs in its digital cordless phones.

“Communications are increasingly done over IP, and our goal is to exceed user expectations with our VoIP telephony productss,” said C.H. Tong, president of VTech Telecommunications.

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.

The SIP cordless desktop phones incorporate DECT, CAT-iq and DECT 6.0 with an adjustable coverage area to deliver improved clarity and installation management.

“VTech 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,” said Jalal Bagherli, CEO of Dialog.

The Dialog SC14452 VoIP IC features a 16-bit CompactRISC processor and two user-programmable Gen2DSPs to deliver 240-MIPS of computational power. It integrates a 32KHz wideband audio codec, Class D amplifier and PAEC (Perfect Acoustic Echo Canceller).
