ST70134A - Brand New STMicroelectronics IC Chips
-
Description
The ST70134A is an ADSL modem chip set with ATM interface that provides all the active functions required to build a complete ATM-based ADSL modem. It operates in the CPE end of the loop (ATU-R mode) and employs Discrete MultiTone modulation as specified in ANSI T1.413. With Reed-Solomon forward error correction and Trellis coding, it offers maximum noise immunity. The chip set includes rate adaptation capabilities and allows for attenuation of the signal in case of short loops or large echo.
Specifications and Features
- Compliance with ANSI T1.413 Issue 1 & Issue 2
- Compliance with G.992.1 (full rate) & G.992.2 (G. Lite)
