TRANSFORMER SOURCES
Table B–1 lists sourcing information for the transformers used in the MC145572 line interface circuit.
NOTES:
2B1Q INTERFACE TRANSFORMER SPECIFICATION
A list of third party vendors and current qualification status appear in Table B–1. The transformer
reference schematic appears in Figure B–1. The specifications in Table B–2 apply to the design of
the U–interface transformer.
Any transformer manufactured to this specification must be verified for compliant transmission perfor-
mance. It is also suggested that transformers manufactured for use in loop powered systems be
required to remain within specification up to the maximum loop current which may be as high as
60 mA.

Manufacturer
Motorola has conducted limited evaluation of third party components for use with the
MC145572. This limited review suggests that the components included here appear to be
suitable for applications using the MC145572. However, the evaluation did not include all
specifications or parameters that may be applicable to particular designs, and the vendors
included here represent only a partial list of component manufacturers. Motorola does not
guarantee that these third party components will work in all applications. It is the responsi-
bility of the equipment designer to verify that these components are suitable for their
intended application.
