In this catalog, turns ratio is expressed as “primary:secondary”. The term “CT” designates a center tapped winding. The term “CS” designates a split center tap winding. A center tapped winding can be created by connecting two ends of a split center winding together on the printed circuit board. In ISDN-S applications, the primary winding is the line side transformer winding. D. National recommends a 1:2 receive transformer, but used as a 1:1 ratio by connecting only half the secondary winding. See National’s application note. E. PE-65950, PE-68613 and PE-65853 are recommended for use with Siemens PEB 2080/2085 and help in meeting the required longitudinal balance. F. Standard packaging for all chokes and transformers listed in this catalog is anti-static tubes. Optional anti-static tray packaging can be ordered for the surface mount SC-1 and LA-1 packages by adding an “R” suffix to the part number, (ie: PE-65795R). Optional tape and reel packaging can be ordered for all surface mount packages by adding a “T” suffix to the part number, (ie: PE-65795T). B. The minimum primary inductance and the maximum distributed capacitance satisfy the transmitter output and receiver input impedance requirements of CCITT I.430 for both the TE and the NT. The maximum distributed capacitance allows sufficient margin for the capacitance of the IC and a protection diode network. It is consistent with the overall maximum value specified and the permitted length of the basic access TE cord. G. For PE-65854, OCL at -40°C is 27 µH minimum. For maximum performance use windings (1-8) and (2-7) as a pair and windings (3-6) and (4-5) as a pair. C. The maximum specified unbalanced DC current capability is based on 20 mH minimum primary OCL. H. For transformers and choke modules, refer to data sheet T632.

Typical ISDN S-Interface Application Circuit 1. General Information – The S-interface is the standardized four-wire digital telephone access point defined by the CCITT I-series recommendations for the Integrated Services Digital Network. This “basic rate access” accommodates two 64Kbps “B-channels” for information, one 16Kbps “D-channel” intended for signaling and control, and 48 Kbps for framing and other purposes, giving a total rate of 192Kbps. The CCITT physical layer recommends that the user network interface be transformer coupled. A typical application circuit is presented in Figure 1. 2. Longitudinal Balance for Transformers – The longitudinal conversion loss specification in I.430 includes a test setup that is intended for system evaluation, whether TE or NT. Such a test is performed with DC current present. The transformer plays an essential role in achieving the required balance. However, all other elements in the circuit should be also designed to provide the highest possible symmetry. These elements include the protection circuitry, series resistors, chip transmitter output and receiver input, as well as the cables used and the TE cord where applicable. A high level of transformer balance compensates for some circuit AC-unbalance, and assures compliance of the system with I.430 on longitudinal conversion loss (LCL) and signal balance. This is accomplished by a well AC-balanced winding configuration whereby the capacitive coupling between primary and secondary windings is evenly distributed. Also, both halves of the lineside winding are well balanced. The transformers meet the following LCL specifications: The transformer provides isolation for the line card or the terminal from the line. It is also a way to provide phantom power feeding to the terminal over the S-loop. Each end requires a transmit and a receive transformer. Chokes are used in some applications to reduce common mode noise (see note 5). The transformers described in this data sheet are matched to the transceivers offered by the major IC manufacturers listed. The use of a transformer-chip pair assures that all requirements of CCITT I.430 are met with respect to pulse waveform templates, impedance and longitudinal balance. In addition, the transformers provide the isolation voltages required by the regulatory agencies and are capable of passing surge voltage tests. • 10kHz to 300kHz: 60dB minimum • 300kHz to 1MHz: Minimum value decreasing 20dB/decade.

Longitudinal Balance Test Circuit (continued from previous page) A recommended test setup is shown in Figure 2. A high inductance “low frequency” common mode choke, such as PE-65950 or PE-65853, is recommended to improve balance, or to correct inherent unbalances of some circuits. 6. Surge Voltage Capability for Transformers and Chokes 4. Impedance Requirements – The requirements for minimum impedance in the inactive and powered-down states are expressed by impedance templates for both transmitter and receiver in NT and TE. At the low frequency end of 1MHz, it is reasonable to assume that the impedance seen from the line is entirely capacitive. The maximum capacitance budget, derived from the templates, is somewhat different for the NT and the TE. Contributors to the total capacitance are: the chip output, the protection circuit, the transformer, common mode choke and any other element that may be present. In the TE case, there is also the maximum allowable TE cord impedance. Here the maximum budget is 800pF. As a rule, the capacitances should be kept as low as possible in the interface circuit design. With the specified transformer capacitances, it is possible to remain within budget and have a reasonable margin for measurement errors. 7. Behavior Under Fault Conditions – Telephony voltages may accidentally appear on the ISDN S-Interface line to the transformer. The transformer will withstand a DC current of 0.5 Amps for 15 minutes without permanent damage. Such current may be caused by the telephone central battery. The transformer will also survive ringing voltages. These are nominally 120V or 200V maximum at 20 to 60Hz, limited by 1500Ω resistive or 400 to 600Ω inductive limiting. These may cause peak currents. • Longitudinal Voltage Peak: 2,400V 10/700µsec • Metallic Voltage Peak: 800V 10/560µsec 8. Flammability – Materials used in the products are recognized UL94-VO. Products meet the requirements of IEC 695-2-2 (Needle Flame Test). 5. Common Mode Chokes – The “high frequency” 4-wire common mode chokes shown on pages 7 and 8 provide an effective means of compliance with national and international regulations on EMI. They are designed to be used in conjunction with either Pulse’s ISDN S-Interface or T1/CEPT transformers as shown in Figure 1. A high inductance “low frequency” common mode choke is recommended to improve balance, or to correct inherent unbalances of some ISDN S-Interface circuits.
