2. General 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.
