Product Summary
The AD6437BS is a complete chipset. Itadds trellis coding, ATM (UTOPIA 2) interface, and new framing modes for improved long reach performance. By incorporating all required components, including controller, analog front-end, driver/receiver and software, it significantly reduces system development time and risk. The same chipset is used for CO (central office) and RT (remote terminal) applications.
