DESCRIPTION

P3902 is designed for Central Office and Customer

Premises ADSL over POTS applications using

TI TNETD3000, and Central Office ADSL over

POTS applications using TI TNETD4000.

P3902 is certified to standards IEC 950 and

UL 60950 for supplementary insulation, 250V

working voltage. P3902 is a UL Recognized

Component and is supported by an IEC CB Test

Certificate.

The part is completely lead-free and suitable for

lead-free and conventional processing.

The safety system yields very low transformer

parasitics, ensuring that P3902 exhibits excellent

frequency response and balance; in combination

with its good harmonic distortion performance,

P3902 is ideally suited to low cost yet demanding

ADSL applications.
