Introduction New applications such as video-ondemand, teleworking, telelearning generate the demand for additional bandwidth. Internet access with xdsl (Digital Subscriber Line) is the fastest growing broadband technology. xdsl uses the ordinary telephone line with twisted copper pairs in a frequency range of 0 Hz to 30 MHz. t present the most popular variant is DSL. The typical configuration at the customer premises combines a modem and a POTS splitter to divide voice and data signals. The layout in the central office is displayed below (Figure ). Ferrite transformers are used in different functions, such as high-pass and low-pass filters, impedance matching and insulation transformers. The cost of upgrading a telephone network to broadband is directly related to the distance from the central office to the provider or the transmitted data rate. Ferrite material is an essential component for increasing the transmission rate and the range of the service.

New core shapes with optimized geometry and downscaled dimensions were also introduced in the POS product range: PX 7/9, PX 0, PO 3 and P 5. This application note looks in detail at the excellent characteristics of innovative POS ferrite products to meet requirements for THD, insertion loss and loop length.

Optimized Ferrite ores for xdsl pplications For xdsl line transformers the P 3 ferrite core in T38 is state-of-the-art. POS has created new products for xdsl line transformers, such as PX cores in the specially developed T66 ferrite material. These new products increase loop reach at a given data rate for xdsl applications. The major goal of all developments is miniaturization of the line transformer without any performance degradation. The lines per board can be increased, which enables further cost reduction. New core shapes Total harmonic distortion (THD) is currently the target parameter for xdsl transformers. The impact of core geometry on THD can be described by the core distortion factor (DF) ). y optimizing the geometry of the new PX cores 2), the DF, and thus THD, was significantly reduced compared to P cores with the same footprint (Figure 3). Figure 4, page 5, shows the effect of geometry on loop reach as measured in an TI0 DSL evaluation board. y using an PX 7/9 core instead of an P 7, loop reach can be substantially improved. ) POS Data ook, page 28 2) Utility model No.: D U 22 209.0, patent pending Figure 3: DF versus footprint for the P core family 0 P 5 DF [mm -4.5 ] PX 7/9 P 7 P 0 PX 0 P 3 0. 0 00 300 Footprint [mm 2 ] PO 3 4 POS G
PX 0 has the same outer dimensions as P 0. PX 7/9 combines the height of P 3 with the small footprint of P 7. PX cores are suited for use in a central office (.O.) because the number of lines per board can be increased. For customer premises (.P..), lower transformer height is often required. PO 3, a low-profile version of P 3, was optimized for this application. ll coils used with P 3 can also be used with PO 3 without any loss in performance. Tight tolerances of the inductance factor L are required for xdsl line transformers. The L tolerances of PO 3 and PX 0 are the same as those of P 3 and P 0. ut PX 7/9 offers tighter L tolerances than P 7. The core geometry features of PX 7/9 permit the same L tolerance as P 3.

Different ferrite materials for different xdsl applications In contrast to DSL, SHDSL is a rate adaptive technology. To increase loop reach, bit rate is lowered by decreasing bandwidth. lso, the voice channels are inserted in the data stream so that the band starts at 0 Hz. So the requirement for the transformer means a lower, narrower band compared to DSL, and can be well correlated to the THD response. Low hysteresis losses over frequency and temperature make T57 the ideal material for SHDSL. The DSL band lies above the separate voice channel in a frequency band higher than SHDSL (28 khz to. MHz). Measuring THD at a single frequency cannot adequately describe transformer behavior. Direct measurement of the reach is necessary. T66 ferrite material was consequently developed for DSL requirements. T66 is specially optimized for longer reach and higher data rate. Measured results (Figure 5, page 5) show the clear advantage of T66 compared to T38. Summary The new PX and PO core shapes enable further miniaturization. Measurement of data rate as a function of loop reach shows the pronounced advantage of PX cores versus the standard P. For DSL applications the reach or data rate can also be improved by the new T66 ferrite material. The PX 7/9 core in T66 achieves virtually the same performance as P 3 in T38. oth the new PX core shape and the new T66 material mean a large step in the miniaturization process of xdsl line transformers.

learance and reepage Distances In the design of transformers, especially for the telecom sector, compliance with different local established standards (N 60950, I 950, UL 950/S 950, S/NZS 3260) is becoming increasingly important. Particularly the requirements of clearance and creepage distances affect the design of coil formers. Our design (PX 7/9, PX 0, P 3, PO 3) fulfills the following requirements according to N 60950: Supplementary insulation Working voltage Vac Pollution degree 2 reepage distance of 2.5 mm (TI III) learance distance of 2.0 mm Test voltage 500 Vac Our design adheres to the requirement between the primary (e.g. pin -side) and secondary winding (other side). Supplementary insulation: Independent insulation applied in addition to basic insulation in case of a fault in the basic insulation. learance distance: learance is the shortest distance between two conductive parts measured through air. reepage distance: reepage is the shortest path between two conductive parts measured along the surface of the insulation. Pollution degree 2: Occasionally, temporary conductivity caused by condensation must be expected (example: product used in typical office environment). xtended outer wire slots (patent pending) In addition to the clearance and creepage requirements between pin-core-pin, the transformer designer must be concerned with the distances between the primary and secondary winding. In this situation we can offer extended outer wire slots, where the wrapped wires dive into the side flange of the coil former and do not disturb higher layers of winding or insulation layers. It will also help to meet the requirements of creepage distances; otherwise a triple-insulated wire is used.
