Extended Temperature Range Models -- For extended temperature range transformers (-40C to +85C operating temperature range), OCL (Open Circuit Inductance) is specified at both -40C and +25C. At -40C, OCL is 600 H minimum. All other parameters are specified at +25C only. 2. Turns ratio is specified primary: secondary (CT = Center Tap). 3. 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. T1176T). Application Notes 1. Flammability -- Materials used in the products are recognized as UL94-VO approved. Products meet the requirements of IEC 695-2-2 (Needle Flame Test). 2. Balance Characteristics -- The transformers meet the requirements for longitudinal balance of FCC part 68. 3. Common Mode Rejection Ratio -- the CMRR for all transformers is better than 50 dB at 1 MHz. A typical test circuit is shown below. 4. 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 65 dB or better. This result was established with the test circuit shown below. 5. 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 50-100 KHz 100 KHz-2 MHz 2-3 MHz Return Loss XMIT RCV 6. 9 dB 12 dB 15 dB 18 dB 11 dB 14 dB 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.
