DESCRIPTION
P3065 is intended for data communications to
33,600 bits/second data rates. P3065 is specifically
designed to be easily matched to both 600 ohm and
complex impedance telephone lines, using a
minimum of external components.
P3065 also exhibits stable characteristics over its
operating temperature range to maximize data
throughput
under
varying
environmental
conditions without the need for modem retraining.
P3065 is certified to IEC 60950 and UL 60950.
P3065 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.

Notes
1. Third harmonic typically exceeds other
harmonics by 10dB.
2. Components are 100% tested at 6.5kV DC.
3. Caution: do not pass DC through windings.
Telephone line current, etc. must be diverted
using semiconductor line hold circuit.
4. At signal levels greater than 100mV, Lp will
increase and Rp will decrease slightly but the
effect is usually favourable to the return loss
characteristic.

Figure 3 gives flat RX and TX responses against
the reference impedance (typically around ±0.5dB
300Hz - 3.4kHz). Return loss is typically better
than 20dB. The 120nF capacitor should be of a
temperature stable dielectric.
In practice, the
100ohm resistor will normally connect to a low
impedance TX output.
In practice, the 820ohm resistor will normally
connect to a low impedance TX output. The 68nF
capacitor, which should be of a temperature
stable dielectric, should be placed in parallel with
the 820ohm resistor (rather than in parallel with
the transformer winding) to obtain good TX
flatness.
For circuits with existing board drillings, figure 4
gives good return loss (>20dB) against the
reference impedance, but TX and RX flatness are
degraded by the use of this topology.
For recommended matching to other reference
impedances please contact Profec Technologies.
