OCL (primary inductance) is measured at the primary winding. Turns ratio is specified primary: secondary. (CT = Center Tap). 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 (100Ω) and CEPT (75Ω & 120Ω). For specific connection information and resistor values, refer to IC vendors' data book. D. Dual Ratio Transformer (T1071, T1111 and T1145) — 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 Turns Secondary Turns Secondary Number Ratio 1 Pins Ratio 2 Pins 1:1 40-39 1:1.26 40-38 T1071 1:1 35-34 1:1.26 35-33 and 1:1 30-29 1:1.26 30-28 T1111 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 T1145 1:2 30-29 1:2.4 30-28 1:2 23-22 1:2.4 23-21 E. Standard packaging 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. T1063T). 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.

T1/E1/CEPT/ISDN-PRI TRANSFORMERS Quad Port T1/E1 with 8 Transformers, 1500Vrms 1. ET Product — All coils have an ET product of 10V-µsec minimum. 2. Flammability — Materials used in the products are recognized as UL94-VO approved. Products meet the requirements of IEC 695-2-2 (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. 5. Crosstalk Attenuation — In the 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 65dB or better. This result was established with the test circuit shown below. 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 within the situations where they are applicable. Frequency 50-100kHz 100kHz-2MHz 2-3MHz Return Loss XMIT 9dB 15dB 11dB RCV 12dB 18dB 14dB 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 cur- rent suppression devices: Metallic Voltage: 800V peak, 10/560µsec Longitudinal Voltage: 2,400V peak, 10/700µsec 8. Isolation Voltage — 100% of transformers are tested during production to the specified isolation voltage level. 9. General Information — The transformers are specifically designed for use in 1.544Mbps (T1), 2.048Mbps (CEPT) and ISDN Primary rate (PRI) interface applications. They are matched to the majority of the l ine 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 -65dB or better.
