TOKEN RING ISOLATION TRANSFORMERS
Designed for 4 and 16 Mbps Applications
Application Notes for Surface Mount:
These transformers are designed for use in Token Ring applications that support both 4 Mbps and 16 Mbps data rates. The varying turns ratios allow for maximum design flexibility in either DTE or MAU applications. For information on combined filter and transformer modules that support either IBM and National Semiconductor, or Texas Instruments Token Ring chip sets, contact Pulse today.

Application Note for Surface Mount:
A combined Token Ring and 10Base-T application circuit is shown below. The suggested application circuit supports either Token Ring UTP or 10Base-T Ethernet media interface. The 23Z354SM was designed to provide isolation and impedance matching for dual protocol UTP media applications. The application circuit provides all necessary components to implement a complete magnetics and media interface for 10Base-T and Token Ring UTP media. Transformers T2 and T4 provide isolation and impedance matching for Token Ring UTP media interface. Transformer T3 provides phantom interface to the media. Filter F2 is the necessary differential filtering in compliance with IEEE 802.5 and FCC emission requirements. An identical F1 filter, included in the receiver path, eliminates high frequency noise on the receive channel and protects against FCC radiated emissions.
RJ-45 (UTP)
Application Note for Through Hole:
These transformers are specifically designed for use in IEEE 802.5 Token Ring applications at either 4 Mbps or 16 Mbps data rates. The varying turns ratios allow the product to be used in either DTE or MAU applications. Single and dual package options provide further flexibility for board layouts.
DTE Front End
The 23Z111 and 23Z379 can provide 100 to 150 impedance transformation. The PE-63838-001, PE-67537, 23Z110, 23Z112, 23Z379, and the 23Z807 can provide 600 to 150 conversion. The 23Z111 and 23Z807 provide taps for 100 and 150 outputs.
