T608.U (05/12) T1/Cept/ISDN-PRI Transformers Application Notes 1. Extended Temperature Range Models - For extended temperature range transformers (-40�C to +85�C operating temperature range), OCL (Open Circuit Inductance for the primary winding) is specified at both -40�C and +25�C. At -40�C, OCL is 600 μH minimum for all low temperature models. All other paratmeters are specified at +25C only. Standard temperature range is 0�C to +70�C. 2. ET Product - All coils have an ET product of 10 V-μsec minimum. 3. Flammability - Materials used in the products are recognized as UL94-VO approved. Products meet the requiremens of IEC 695-2-2 (Needle Flame Test). 4. Balance Characteristics - The transformers meet the requirements for longitudinal balance of FCC part 68. 5. Common Moe Rejection Ratio - The CMRR for all transformers is better than 50 dB at 1 MHz. A typical test circuit is shown below. HP-8751A P1 P2 Frequency Return Loss TX RX XFMR 100:50 BALUN 6. Crosstalk Attentuation - In the dual packages, which contain transmit and receive transformers side by side, sufficient crosstalk attenuation is achieved by the inherent characteristics of the toroid cores as well as by their proper positioning. The crosstalk attenuation is typically 50 dB or better from 100 kHz to 10 MHz. This result was established with the test circuit shown below. HP-8751A 50:100 BALUN P1 P2 100 100 100 kHz-2 MHz 2-3 MHz 9 dB 12 dB 15 dB 18 dB 11 dB 14 dB 8. Surge Voltage Capability - All transformers and chokes meet surge voltage tests according to the most stringent regulatory documents when system designs include the proper voltage and current suppression devices: Metallic Voltage: Longitudinal Voltage: 800 V peak, 10/560 μsec 2,400 V peak, 10/700 μsec 9. Isolation Voltage - 100% of transformers are tested during production to the specified isolation voltage level. 10. Safety Agency Recognition - Parts listed as “Recognized” or “Certified” meet Underwriter Laboratories, UL 1459 and UL 1950 per file E133523 (S). Transformers with Reinforced Insulation according to IEC950, such as PE-68646NL (pg. 3) is certified by the following organizations: Code 50:100 BALUN 50-100 kHz Certificate Information T TUV, EN60 950/EN 41003, Cert. R9371358, reinforced insulation U UL 1459/UL1950, File E133523 (S), reinforced insulation 11. General Information - The transformers are specifically designed for use in 1.544 Mbps (T1), 2.048 Mbps (CEPT) and ISDN Primary rate (PRI) interface applications. They are matched to the majority of the line interface transceiver ICs currently available. Use of the proper transformer allows the interface circuit to comply with ITU-T G.703 and other standards regarding pulse waveform, return loss, and balance. 12. Common Mode Chokes - The “high-frequency” 4-lines common mode chokes shown in this data sheet provide an effective means of compliance with national and international regulations on EMI. They are designed to be used in conjunction with Pulse’s T1/ CEPT transformers as shown in the typical application below. Crosstalk is typically -70 dB at 1 MHz and -55 dB at 10 MHz. Typical Application Transformer Transformer XFMR 100:50 BALUN 7. Return Loss - ITU-T G.703 and European national regulatory documents specify minimum return loss levels. The transformers will allow these limits to be complied within situations where they are applicable.

Safety Agency approvals pending. H. The turns ratio of these devices have been designed, in conjunction with semiconductor vendor recommendations, to allow connections to various terminations (e.g 75 Ω or 120 Ω with the same transformer). For 75 Ω termination, the PEB 2235 requires the following turns ratio: 1:1.57 (TX) and 1:1.26 (RX) which can be achieved using pins (1-2):(15-16) for TX and (1011):(5-8) for RX. For 120 Ω, the following turns ratio are required: 1:2 (TX) and 1:1 (RX), which are pins (1-2):(16-14) for TX and (9-11):(5-8) for RX. C. To make a 1CT:1 ratio from a 1CT: 2CT ratio, use only one half of the secondary (2CT) winding. D. For Reinforced 3 kVrms Dual SMT Transformers, refer to data sheet T617. For Octal SMT Transformers, refer to data sheet T622. E. Dual Ratio Transformers: These transformers have tapped secondary windings to provide two turns ratios (T/R).
