communications solution that is flexible enough to carry you into the future.
The PCT2303W chip set is an integrated direct access arrangement (DAA) and Codec that provides a programmable
line interface to meet international telephone line requirements. The PCT2303W chip set is available in two 16-pin
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.
