Notes:
1. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the
part number (i.e. PE-53914L becomes PE-53914LT). Pulse complies to industry
standard tape and reel specification EIA481.
2. The “NL” suffix indicates an RoHS-compliant part number. Non-NL suffixed
parts are not necessarily RoHS compliant, but are electrically and mechanically
equivalent to NL versions. If a part number does not have the “NL”
suffix, but an RoHS compliant versions is required, please contact
Pulse for availability.
3. The temperature of the component (ambient plus temperature rise)
must be within the stated operating temperature range.

SMT Common Mode Inductors
0.5A to 3.6A
Application
These transformers have been designed for use at
the interface between line driver and receiver and
the interconnecting medium in Digital Audio Data
Transmission Systems according to AES 3-199X or
IEC 958. In such systems, two channels of periodically
sampled and uniformly quantized audio signals are
transmit on a single shielded twisted pair.
The electrical parameters of the interface are based on
those of CCITT V.II or balanced voltage digital circuits
which allow signal transmission up to a few hundred
meters. The isolation transformers are essential in
improving the balance of the transmitter and the receiver
circuitry, and reducing common mode noise and EMI.
These transformers are recommended for use with the
Cirrus Logic CS8401, CS8402, CS8403 and CS8404
“Digital Audio Interface Transmit Device. The schematic
below represents an implementation of transmit and
receive circuits using isolation transformers at both ends.
Equalization in the receiver may permit to increase the
length of the interconnecting cable.
