INTRODUCTION
The LU97 chip set is an integrated direct
access arrangement (DAA) that provides a
programmable line interface to meet
international telephone line requirements.
The LU97 chip set is available in two 16-pin
small outline packages (AC‘97 interface on
CSP1037 and telephone line interface on
CSP1037A/B). The chip set eliminates the need
for an AFE, an isolation transformer, relays,
opto-isolators, and a 2-wire to 4-wire hybrid.
The LU97 chip set dramatically reduces the
number of discrete components and cost
required to achieve compliance with
international regulatory requirements.
The CSP1037 complies with AC‘97/MC‘97
Interface Specification Rev. 2.1.
