small outline packages (AC’97 interface on PCT303A and phone-line interface on PCT303W). The chip set
eliminates the need for an AFE, an isolation transformer, relays, opto-isolators, and 2-to 4-wire hybrid. The
PCT2303W chip set dramatically reduces the number of discrete components and cost required to achieve
compliance with international regulatory requirements. The PCT2303W complies with AC’97 Interface specification
Rev. 2.1.
The chip set is fully programmable to meet world-wide telephone line interface requirements including those
described by CTR21, NET4, JATE, FCC, and various country-specific PTT specifications. The programmable
parameters of the PCT2303W chip set include AC termination, DC termination, ringer impedance, and ringer
threshold. The PCT2303W chip set has been designed to meet stringent world-wide requirements for out-of-band
energy, billing-tone immunity, lightning surges, and safety requirements.
