92 modems ∗ Line matching 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.
