ELECTRICAL SPECIFICATIONS
RECEIVER SPECIFICATIONS FOR CMI INTERFACE (Transformer-coupled)
Consult application note for reference schematic, layout guidelines, and recommended transformers.
The input signal is assumed compliant with ITU-T G.703 and can be attenuated by the dispersive loss of a
cable. The minimum cable loss is 0dB and the maximum is –12.7dB at 78MHz.
The “Worst Case” line corresponds to the ITU-T G.703 recommendation. The “Typical” line corresponds to a
typical installation referred to in ANSI T1.102-1993. The receiver is tested using the cable model. It is a lumped
element approximation of the “Worst Case” line.
