Extended Temperature Range Models - For extended Frequency 50-100 kHz 100 kHz-2 MHz 2-3 MHz temperature range transformers (-40�C to +85�C Return Loss operating temperature range), OCL (Open Circuit TX 9 dB 15 dB 11 dB Inductance for the primary winding) is specified at both RX 12 dB 18 dB 14 dB -40�C and +25�C. At -40�C, OCL is 600 μH minimum 8. Surge Voltage Capability - All transformers and chokes for all low temperature models. All other paratmeters meet surge voltage tests according to the most are specified at +25C only. Standard temperature range stringent regulatory documents when system designs is 0�C to +70�C. include the proper voltage and current suppression devices: 2. ET Product - All coils have an ET product of 10 V-μsec minimum. Metallic Voltage: 800 V peak, 10/560 μsec Longitudinal Voltage: 2,400 V peak, 10/700 μsec 3. Flammability - Materials used in the products are 9. Isolation Voltage - 100% of transformers are tested recognized as UL94-VO approved. Products meet the during production to the specified isolation voltage requiremens of IEC 695-2-2 (Needle Flame Test). level. 4. Balance Characteristics - The transformers meet the 10. Safety Agency Recognition - Parts listed as requirements for longitudinal balance of FCC part 68. “Recognized” or “Certified” meet Underwriter Laboratories, UL 1459 and UL 1950 per file E133523 5. Common Moe Rejection Ratio - The CMRR for all (S). transformers is better than 50 dB at 1 MHz. A typical test circuit is shown below. Transformers with Reinforced Insulation according to IEC950, such as PE-68646NL (pg. 3) is certified by HP-8751A the following organizations: P1P2 Code Certificate Information T TUV, EN60 950/EN 41003, Cert. R9371358, reinforced insulation U UL 1459/UL1950, File E133523 (S), reinforced insulation 50:100 XFMR 100:50 BALUN BALUN 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. 6. Crosstalk Attentuation - In the dual packages, which They are matched to the majority of the line interface contain transmit and receive transformers side by side, transceiver ICs currently available. Use of the proper sufficient crosstalk attenuation is achieved by the transformer allows the interface circuit to comply inherent characteristics of the toroid cores as well as with ITU-T G.703 and other standards regarding pulse by their proper positioning. The crosstalk attenuation waveform, return loss, and balance. is typically 50 dB or better from 100 kHz to 10 MHz. This result was established with the test circuit shown 12. Common Mode Chokes - The “high-frequency” 4-lines below. common mode chokes shown in this data sheet HP-8751A provide an effective means of compliance with national 50:100 BALUN and international regulations on EMI. They are P1P2 designed to be used in conjunction with Pulse’s T1/ 100 CEPT transformers as shown in the typical application below. Crosstalk is typically -70 dB at 1 MHz and -55 dB at 10 MHz. 100 Typical Application Transformer Transformer XFMR 100:50 BALUN IC IC 7. Return Loss - ITU-T G.703 and European national XMiT RCVE regulatory documents specify minimum return loss levels. The transformers will allow these limits to be complied within situations where they are applicable. Choke Choke RCVE XMIT 7 pulseelectronics.com T608.W(5/17)
