DESCRIPTION
P5033 is intended for low cost V.90 and V.92 (56kbps) modems and other high-speed applications. It is a direct substitute for P3356, being mechanically compatible and having identical signal/distortion and matching characteristics, and suitable for supplementary insulation, 250V working. P5033 uses patented design and construction methods to achieve excellent signal performance and safety isolation to international standards. The part is completely lead-free, compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional processing. P5033 has exceptionally flat frequency response from 30Hz to 10kHz, a 3dB bandwidth of 60kHz and requires only the very simplest of matching to achieve good return loss and transhybrid loss across the voiceband, with very low levels of signal distortion at signal frequencies as low as 150Hz. P5033 also exhibits stable characteristics over its full operating temperature range to maximize data throughput under varying environmental conditions without the need for modem retraining. P5033 is certified to IEC 60950 and UL 60950. P5033 is a UL Recognized Component and is supported by an IEC CB certificate.

Notes: Equivalent Circuit 1. Third harmonic typically exceeds other Fig. 1 harmonics by 10dB. 2. Components are 100% tested at 3.25kVDC. 3. Caution: do not pass DC through windings. IDEAL Telephone line current must be diverted using ½L ½L 1:1 semiconductor line hold circuit or choke. 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. 5. Return loss and transhybrid loss can be improved to 30dB in improved matching circuit. The values shown relate to the simplest configuration, Fig. 2. 6. At signal frequencies, the primary and secondary resistance appear in series with the load and therefore present a sum of resistances in the range 165-207Ω in common with P3356.

MATCHING RECOMMENDATIONS
The following recommendations start with the simplest implementations and progress to enhanced performance utilizing additional components. Good performance is achieved even with the simplest configurations. The implementations assume a low impedance balanced TX drive and a relatively high impedance RX input, as is commonly available, though use with other TX/RX arrangements is straightforward. Note that there are no changes to components on the line side, or in the hybrid, whether 600Ω or complex reference impedance selected, thus assisting country configuration. For complex impedance, the matching circuits derived are suitable for reference impedances of the type 270 + 750//150nF e.g. European CTR21 and 220 + 820//120nF (or 115nF) e.g. Australia, South Africa, etc., and yield similar performance characteristics. For other impedances, please contact Profec Technologies. Minimum Cost Implementations
