NXP的PNX80xx系列廣泛應用在中低檔數字無繩電話市場的座機和手機,能適合所有主要的無繩電話標準如DECT, DECT 6.0,WDCT 2.4和WDCT 5.8,也可用在PC主機的USB軟電話(DECT Dongles)以及多媒體VoIP手機.
PNX80xx系列中每個器件都包括有功能強大的ARM968E-S處理器和優化的硬件架構,提供的特性如CAT-iq, USB softphone,寬帶音頻,寬帶合成,寬帶全上工程免提,以及寬帶多和弦.架構上還提供嵌入式RAM和ROM存儲器,四通路硬件ADPCM,接口電路,以及帶放大器的音頻CODEC,輔助的ADC和DAC,帶功率放大器的嵌入式收發器和功率管理等功能.
Designed for the low-end, mid-range, and USB softphone segments of the digital-cordless market, this single-chip family combines state-of-the-art RF functions with a powerful ARM9 baseband and provides fast, fl exible design-in for all DECT and WDCT standards used worldwide.
NXP leads the market for digital-cordless ICs and worked closely with major phone manufacturers to define features and functions of the PNX80xx series. The result is unmatched performance with more features and easier design-in, at a lower overall cost.
Each device is built around a powerful ARM968E-S processor with an optimized Harvard architecture that can accommodate all the latest features, including CAT-iq, USB softphone, wideband audio, wideband synthesis, wideband full-duplex handsfree, and wideband polyphony. The architecture also offers embedded RAM and ROM memories, a four-channel hardware ADPCM, interface circuits, audio codecs with amplifier, auxiliary A/D and D/A conversion, an embedded transceiver with power amplifier, and power management functions.
A state-of-the-art radio transceiver extends the radio range and delivers improved audio quality. It offers output power control (-17 to 27 dBm), increased sensitivity (-99 dBm DECT and -102 dBm WDCT 2.4), and reduced component count. A fast- switching PLL enables zero blind slots radio.
Multiple on-chip interfaces provide simple access to a range of peripherals. There are 29 multiplexed GPIO with wake-up features, one I2C-bus and two high-speed SPI interfaces, a pulse width modulator (PWM), a keyboard scanner, a buzzer interface, a UART, a USB interface with twelve endpoints and control, and a digital-audio interface that combines I2S, IOM, and PCM.
All the ICs use the same API, so software is easy to port and integrate. The devices within each series are also based on the same development platform and are pin-to-pin compatible. This greatly simplifies the design process and lets you use a single software stack to create a range of products with a high degree of differentiation.
To address different standards, every device has an integrated, fully programmable Burst Mode Processor (BMP) proven for DECT, WDCT, DECT 6.0, and Bluetooth. Third-party software, widely available for the ARM9 architecture, is easy to port onto the design.
Large on-chip RAM and ROM memories increase the options for creativity and simplify logistics, with fewer ROM versions that combine product range and country version.
The integrated 4-kB patch RAM mechanism reduces time-to-market and maximizes production flexibility, by making it easy to fix bugs and support product evolutions. The family includes Flash versions, versions with a cost-optimized supply concept, USB, up to two integrated codecs, and various ROM and RAM footprints.
