USB/RJ45 Application Note
This line of Integrated Connector Modules are specifically
designed for the implementation of a 10Base-T, 100Base-TX
and 1000Base-TX transmission over data-grade unshielded
twisted pair cable (UTP-3, 5/5e).
providing these 10/100/1000 solutions, thereby assuring
compatibility with each transceiver.
JW0 and JY0 series meet the stringent open circuit inductance
requirements of IEEE. When an 8mA DC current is applied across
the transformer windings, the transformer will provide at least
350µH. The transformers used in each module also provide
1500Vrms minimum isolation, wide bandwidth with minimal
attenuation and fast rise times to minimize system level jitter.
The connectors provide excellent EMI filtering and are suitable
for Desktop PC, Embedded Systems and Multiport Applications.
Pulse has worked closely with the leading IC manufacturers in

PCB Layout Recommendations:
2. Connections to ground should be as short as possible.
1. For maximum EMI suppression (electromagnetic interference)
place the decoupling capacitors adjacent to Vcc and 50Ω
connections.
3. Connections between the 10/100/1000 IC and the connector
should be direct (ideally no change in direction) and of
minimum length.
