Dialog Semiconductor plc has been developing a high performance VoIP phone chipset for at mid high-end desktop phones. The SC14453 is the latest chipset which integrates hardware blocks for best-in-class audio, security and graphics functionality.

The SC14453 is based on the highly efficient and ultra low power 32-bit MIPS M14Kc processor. Additionally, it 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.

The on-board multicore VoIP processor features Dialog’s acoustic echo cancellation and active noise reduction, boosting audio quality for crystal clear voice conversation. It delivers 590MIPS of computational power and integrates stereo analog codecs and a stereo Class D amplifier with 48kHz support.

The SC14453 Green VoIP platform provides a high level of flexibility for wireless and wired extensions to CAT-iq, DECT, WiFi, Bluetooth, LTE, USB and Gigabit Ethernet. The SC14453’s advanced audio DSPs and its symmetric / asymmetric cryptography accelerator can manage eight simultaneous SRTP-secured IP calls, and its powerful graphic engine and LCD controller enable the output of fluid graphic user interfaces onto SVGA (800x600) 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.
