Description

The S5N8944B is a complete ATM-based rate adaptive G.Lite ADSL modem solution with associated F/W and an Analog Front-End (S5N8943). The S5N8944B provides all the digital functions such as ATM TC, FEC codec with interleaver/de-interleaver, adaptive QAM codec, FFT/IFFT, equalizers, digital filters and so on.

There are four interfaces for external communications; UTOPIA-2 interface for direct connection to ATM systems, serial interface for non-ATM applications, 16-bit ADC/DAC interface, and host interface for general CPUs like Intel or Motorola.

The same chipset can be used at both sides of the link, Central Office and Customer Premises Equipment. The S5N8944B uses 17.664MHz Xtal oscillator as a master clock for CO side and 17.664MHz VCXO for CPE.
