The suggested application circuit supports operation over shielded twisted pair or unshielded twisted pair media. Note that both channels are identical in the PE-67583. are dependent upon the individual layout, operating conditions, and specific cabling requirements. Pulse transformers are designed for use in ATM 25.6 Mbps applications that require a low frequency cutoff below 12 KHz. The components and guidelines in this note should serve as a starting point for design. The circuit and layout of an ATM 25.6 interface requires that special attention be given to the selection of components and their placement to reduce induced noise. The optimum external circuit values It is important not to connect both UTP and STP media simultaneously. The module has been optimized to support only one media connection at a time.
