2. General Description
The S5N8952X is a complete ATM-based ADSL modem solution with associated F/W and an Analog Front-End (S5N8951). The S5N8952X provides all the digital functions such as PCI I/F, SAR, ATM framing, channel codec, DMT modulation, and DSP control. There are two interfaces for external communications; PCI bus interface for NIC applications and AD/DA interface. The S5N8952X is optimized for providing NIC solution for CPE, and uses 17.664MHz Xtal oscillator as a master clock.

6. Functional Description
The ADSL modem for customer premises consists of two main chips; ADSL transceiver chip (S5N8952) and analog front-end chip (S5N8951). The analog front-end provides an analog interface with line drivers and hybrid components for connecting to the PSTN. The ADSL Transceiver provides all the digital functions as depicted in Figure 4. DMT inherently transmits an optimized time-variable spectrum. This spectrum is adjusted according to the desired data rate and the transmission characteristics (transfer function and noise spectrum) on each and every subchannel. For this, CO and CPE transmit 256 4kHz-wide tone downstream and upstream respectively to each other during initialization. They measure the quality of each of these received tones and then decide whether a tone has sufficient quality to be used for further transmission and, if so, how much data this tone should carry relative to the other tones that are used. They inform the bit loading informations to each other. In FDM-based DMT (Discrete MultiTone) modulation, the frequency band, 0 to 1.104MHz, is divided into 256 equi-spaced subchannels with 4.3125KHz tone spacing. The frequency band, 26KHz (#6) to 134KHz (#31) is used for the upstream, and 142KHz (#33) to 1.1MHz (#255) for the downstream. The S5N8952 provides PCI bus interface for NIC application and 14-bit AD/DA interface. SAR (Segmentation and Reassembly) and ATM TC (Transmission Convergence) are implemented for ATM cell handling and especially on-chip hardware SAR provides more processing power by reducing the PCI bus traffic than the software SAR. Reed-Solomon error correction with/without interleaver and Trellis coded modulation increase channel noise immunity. Time/frequency-domain equalizers, echo canceller, and digital filters, of which coefficients are adaptively updated according to the channel conditions, enhance the performance of data recovery.
