OCL (primary inductance) is measured at the primary winding. Turns ratio is specified primary: secondary. B. To make a 1CT:1 ratio from a 1CT:2CT ratio, use only one-half of the secondary (2CT) winding. C. It is possible to use the same transformer model for the three impedance levels of T1 (100 W) and CEPT (75 Ω & 120 Ω). For specific connection information and resistor values, refer to IC vendor’s data book. D. Dual Ratio Transformer (T1071NL and T1145NL) - These transformers have tapped secondary windings to provide two turns ratios (T/R). Use the entire primary winding and connect the secondary pins listed below to obtain desired turns ratio: Part Number T1071NL T1145NL Turns Ratio 1 Secondary Pins Turns Ratio 2 Secondary Pins 1:1 40-39 1:1.26 40-38 1:1 35-34 1:1.26 35-33 1:1 30-29 1:1.26 30-28 1:1 25-24 1:1.26 25-23 1:2 40-39 1:2.4 40-38 1:2 33-32 1:2.4 33-31 1:2 30-29 1:2.4 30-28 1:2 23-22 1:2.4 23-21 E. Dual Ratio Transformer for the surface mount package is anti-static tubes. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number, (i.e. T1064NLT). F. 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. All other parameters are specified at +25�C only. Standard temperature range is 0�C to +70�C. Schematics TOU 2 pulseelectronics.com IC Mfr.

ET Product - All coils have an ET product of 10 V-μsec minimum. 8. Isolation Voltage - 100% of transformers are tested during the specified isolation voltage level. 2. Flammability - Materials used in the products are recognized as UL94-VO approved. Products meet the IEC 695-2-2 requirements (Needle Flame Test). 3. Balance Characteristics - The transformers meet the requirements for longitudinal balance of FCC part 68. 4. Common Mode Rejection Ratio - the CMRR for all transformers is better than 50dB at 1MHz. A typical test circuit is shown below. 9. 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. 10. Common Mode Chokes - Additional high-frequency 4-line common mode chokes may be used to provide an effective means of complying with national and international regulations on EMI. The common mode chokes are designed to be used in conjunction with Pulse’s T1/CEPT transformers as shown in the typical application below. Crosstalk is typically -65 dB or better. HP-8751A P1 P2 50:100 BALUN XFMR 100:50 BALUN Typical Application 5. Crosstalk Attentuation - In the packages which contain transmit and receive transformers side by side, sufficient crosstalk attentuation is achieved by the inherent characteristics of the toroid cores as well as by their proper positioning. The crosstalk attentuation is typically 65 dB or better. This result was established with the test circuit shown below. HP-8751A 50:100 BALUN P1 P2 100 100 XFMR 100:50 BALUN 6. 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 with the situations where they are applicable. Frequency 50-100 kHz 10 kHz-2MHz 2-3 MHz Return Loss Transmit 9 dB 15 dB 11 dB Receive 12 dB 18 dB 14 B 7. Surge Voltage Capability - All transformers and chokes meet surge voltage tests according to the most stringent regulatory documents, when used with the proper voltage and current suppression devices: 3 pulseelectronics.com T622.K (04/12) T1/E1/CEPT/ISDN-PRI TRANSFORMERS Quad Port T1/E1 with 8 Transformers, 1500 Vrms RoHS Compliant Number of Part Number Lines High Frequency Common Mode Chokes Turns Ratio (±5%) Electrical Specifications @ 25°C LL C w/w OCL (μH MIN) (pF MAX) (μH MAX) DCR (Ω MAX) Isolation (Vrms MIN) Package/Schematic T8008NL* 16 (8 x 2 line) 1:1 (8 places) 47.0 25 .18 0.40 500 TOU/2 (Surface Mount) PE-65554NL 4 1:1:1:1 24.0 15 .20 0.30 500 IN/1 (Through Hole) PE-65555NL 4 1:1:1:1 8.0 10 .20 0.25 500 IN/1 (Through Hole) PE-65854NL 4 1:1:1:1 47.0 16 .20 0.30 500 SH/1 (Surface Mount) PE-65857NL 4 1:1:1:1 24.0 15 .23 0.30 500 LA/1 (Surface Mount) *Notes: Please see page 1 for TOU mechanical specifications.
