Semiconductors for DECT
DECT RF Transceiver AD6411 provides the complete transmit and receive RF signal processing necessary to implement a digital wireless transceiver based on the Digital Enhanced Cordless Telecommunications (DECT) standard.
The AD1803/AD1804 chipset allows the implementation of a low-cost full Modem DAA Line Interface and codec with minimal external components. The AD1803 can also be used as a stand-alone codec for voice/handset/telephony applications, or as a cellular telephone interface. Modem/Telephony Codec - applications include: Modems (PC and Embedded), Voice and Telephony, Fax Machines, Answering Machines, Speakerphones, PBX Systems, DECT Base Stations, Smart Appliances.
GHz DECT transceiver IC with integrated VC) (PDF File) RF transceiver IC for DECT applications at 2.4 GHz, is a solution for a
wide range of data and voice applications such as residential cordless phones,
WPBX, WLL and WLAN. Along with Atmel's well-known Low-Noise Amplifier/ Power
Amplifier T7024, it forms a complete RF system for 2.4 GHz DECT systems.

DECT Baseband ICs
SC14408 This IC is a backwards compatible successor of the SC14404, with additional Flash & RAM size and UART with DMA, and is designed in 0.25 micron CMOS. The SC14408 combines 3Mb of embedded flash with a CompactRISC core, allowing a very high degree of software flexibility. It has multiple features embedded on one chip, such as programmable radio interface, arm-length hands free, power management and data support. The direct memory access (DMA) supports DECT data applications in products such as tinformation appliances
The SC14406 and SC14407 are the high-end and standard ROM versions of the SC14408.

RTC100S The RTC100S is a Talking Caller ID slave chip. It is capable of pronouncing names using miniature Text-to-Speech (TTS) technology. Our Talking Caller ID technology is used by brands such as Panasonic, Uniden, SBC and others.
RTC102S The RTC102S is a self-contained speech recording chip, intended for integrated telephone answering device (ITAD), digital answering machine (DTAD/TAM) and general purpose voice mail recording. It supports several compression algorithms and features such as remote access, silence removal, comfort noise generation and flexible interface.
RSV100 The RSV100 is a voice dialing and biometric voice recognition chip. It provides a total solution to manufacturers wishing to add voice password or voice tags feature to their products to implement voice dialing, speech recognition and speaker identification/verification.
SE2510L - 1.9 GHz Power Amplifier - A 2-stage power amplifier designed for use in the 1.9GHz DECT band for cordless telephone applications. The device is optimized for 2 cell operation offering 26.5dBm @ 2.2V. The device has a sophisticated bias scheme that keeps power variation to a minimum. The SE2510L contains two discrete power control settings (High/Low power), controllable by a single logic pin. The SE2510L includes a digital enable control for device on/off control. This control also includes a ramping circuit, with the ramp time customizable via an external capacitor. An external resistor sets the SE2510L bias, which eliminates the need to have an external power control circuit.
