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.
