Overview

The PSB 4595 and PSB 4596 two-chip solution forms the complete front end of a modem or fax machine. This Analog Line Interface Solution (ALIS) consists of a DAA, a codec and a hybrid circuit, and bridges the gap between the phone line and the data pump. The analog PSB 4595 is manufactured in low-power BiCMOS technology and the digital PSB 4596 in CMOS technology.

Features

? ALIS substitutes data access arrangement (DAA), codec and hybrid

? Ring detection: level, frequency and cadence

? Programmable to different country requirements

? Programmable DC characteristics

? ALIS supports V.34+ and V.90

? ALIS complies with ETS 300 001 and FCC requirements

? Isolation by digital capacitor interface

? Analog part powered from the tip/ring line by an integrated voltage regulator

? High performance analog-to-digital and digital-toanalog conversion

? DSP-based solution for adapting the transmission behavior, especially for

- AC impedance matching

- trans-hybrid balancing

- frequency response - gain

? Advanced test capabilities:

- digital loops

- analog loops

? High-pass filter in receive path to suppress line interference (50/60 Hz)
