1. Features
Full Compliant with ANSI T1.413 Issue-2, ITU G.992.1 (G.dmt) and G.992.2 (G.lite) FDM based DMT line code Data Rate: over 8Mbps for downstream and 640 Kbps for upstream Reach: 22Kft (6.7 Km)with 24 AWG and 18 Kft (5.5 Km)with 26 AWG Compatible to PCI V2.2 Handles ATM cells with on-chip SAR and connection memory Reed-Solomon forward error correction with interleaver Adaptive frequency and time domain equalizer Trellis coding and echo cancellation Supports dual-latency mode 18m, 1.8V CMOS Technology Operating Temperature: 0 C to 70 C Package Type: 208-LQFP
2. General Description
The modem consists of two main parts; The S5N8943, an analog front-end, provides an analog interface with line drivers and hybrid components to connect the PSTN. The S5N8952 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 with DSP such as PCI bus Interface, ATM SAR, ATM TC and (De)Framer, FEC Codec with (De)interleaver, Adaptive QAM Codec, FFT/IFFT, Equalizers, and Digital Filters. The PCI bus interface of which bus frequency is up to 33MHz, is compilant with PCI specification v2.2, and supports +3.3V or +5V PCI interface for NIC applications. The AD/DA interface provides 4.4MHz sample rate with 14-bit resolution. The S5N8952, which consists of DMT modem and on-chip PCI/SAR, is optimized for providing NIC solution for CPE, and uses 17.664MHz as a master clock.

6. Functional Description
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 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 forward error correction with/without interleaver and Trellis coded modulation increase channel noise immunity. Time/frequency-domain equalizers, echo canceler, and digital filters, of which coefficients are adaptively updated according to the channel conditions, enhance the performance of data recovery.
