DESCRIPTION
P3156 is intended for data communications to V.90
and V.92 (56kbps) data rates. P3156 is specifically
designed to be matched to both 600 ohm and
complex impedance telephone lines, using a
minimum of external components, with very flat TX
and RX frequency responses.
P3156 also exhibits stable characteristics over its
operating temperature range to maximize data
throughput
under
varying
environmental
conditions without the need for modem retraining.
P3156 is certified to IEC 60950 and UL 60950.
P3156 is a UL Recognized Component and is
supported by an IEC CB Test Certificate. The part
is completely lead-free, compliant with RoHS
Directive 2002/95/EC, and suitable for lead-free
and conventional processing.
P3156 has extended flat frequency response from
30Hz to 4kHz with very low levels of signal distortion
at signal frequencies as low as 150Hz.
