DESCRIPTION
The P520X family comprises a range of
transformers, designed for Conexant Smart DAA™
chipsets. They are intended, as part of the Digital
Isolation Barrier, for coupling clock signals and
power between chips on either side of the safety
barrier.
The P520X family provides Supplementary
Insulation for a primary circuit at a working
voltage of 250Vrms and is compliant with
IEC 60950, and UL 60950. The family members
are UL Recognized Components and are
supported by an IEC CB certificate.
The P520X family is compliant with RoHS
Directive 2002/95/EC, and suitable for lead-free
and conventional placement and reflow.
