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.

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.

ETALDOC 479/14 Page 3 of 5 February 2006 PERFORMANCE CHARACTERISTICS 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. 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. 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 recommended matching to other reference impedances please contact Profec Technologies. R ecommended Circuit Fi g 2 470LINE 600 22nF10nF μ4.7 F
