IC Part Number Comments Octal SMT STD Temp EXT Temp Mindspeed (Conexant) Notes from Electrical Specifications Table A. 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 Part Number 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 T1071NL T1145NL 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. to provide two turns ratios (T/R).
