DS2155LNC2+

The DS2155LNC2+ is a two-in-one digital signal processor and analog front end designed for telecommunication applications. It combines digital signal processor (DSP) and analog front end (AFE) functions in a single device, providing a complete solution for voice, data and multimedia applications.

The DS2155LNC2+ is a low-power, single-chip solution that can be used for applications such as voice-over-IP (VoIP) gateways, wireless base station front ends, wireless local loop access systems, wireless "last mile" access systems, portable multimedia devices, ATAs, VoIP phones, and other multimedia applications.

The DS2155LNC2+ combines an AFE (Analog Front End) with a 32-bit dual embedded DSP core. The AFE includes all the necessary interface circuitry, including an audio codec, a single sideband (SSB) modulator, and a SSB demodulator. The AFE also includes TI\'s patented low-distortion transmit pre-filtering, two additional receive filters, and two SPDT relays for antenna switching.

The dual embedded DSP core of the DS2155LNC2+ offers a complete VoIP solution and also allows for data and multimedia applications. The DSP core provides an array of communication algorithms and digital signal processing algorithms for widely used applications, such as encoding and decoding, error correction, forward error correction, echo cancellation, and other digital signal processing algorithms. The DS2155LNC2+ also has on-chip memory and peripherals, such as an external memory interface, on-chip clock generation, timers, and interrupt controllers, which combine to provide a complete system on a chip solution.

In addition to voice applications, the DS2155LNC2+ also supports data applications, such as packet-based radio access networks and machine-to-machine (M2M) communications. The processor supports data transfer speeds up to 8.32 Mbps, which is sufficient for most modem applications. The processor also supports other data-intensive applications, such as digital image processing and video streaming applications.

The DS2155LNC2+ is designed for easy integration and assembly. It satisfies all the necessary requirements for license-free operation and is ready for deployment in existing telecommunication networks. It can be quickly integrated into existing systems, offering hardware and software compatibility, cost savings, and superior performance.

In conclusion, the DS2155LNC2+ is an ideal solution for voice, data, and multimedia applications It provides an AFE that includes all the necessary interface circuitry, a 32-bit dual embedded DSP core for advanced signal processing algorithms, on-chip memory, and peripherals for a complete system on a chip solution. It is compliant with standards for license-free operation, and offers hardware and software compatibility, cost savings, and superior performance.
