PulseJack™
Surface Mount 1x1
JV Application Note
This line of 10/100Base-TX SMT RJ45 1X1 Connector
Magnetics Modules has been specifically designed for
the implementation of a 10Base-T and 100Base-TX
transmission over data-grade unshielded twisted pair
cable (UTP-3, 5e and 6).
isolation, wide bandwidth with minimal attentuation and
fast rise times to minimize system level jitter.
The 1X1 SMT RJ45 connectors manufactured by Pulse
are designed to meet all published specifications after
exposure to surface mount soldering temperatures.
The SMT are robust enough to withstand convection
and infrared reflow solder temperatures. Additionally,
compliant leads provide excellent solder-joint reliability
with a coplanarity of 0.10 (0.004”).
The connectors provide excellent EMI filtering and are
suitable for adapter card and multiport applications. Pulse
has worked closely with the leading IC manufacturers
in providing these 10/100 solutions, thereby assuring
compatibility with each transceiver.
Note: Modules are packaged in trays, unless Tape & Reel is
specified. Please add the suffix “T” for Tape & Reel orders
(ex: JVO006121T). Add the suffix “NL” for RoHS compliant
parts (ex: JV006I21NLT for Trays and JV006I21NLT for
Tape & Reel).
The JC0 series meets the stringent open circuit
inductance requirements imposed by 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
JV006I21 Connector
PCB Layout Recommendations:
1. For maximum EMI suppression (electromagnetic interference)
place the decoupling capacitors adjacent to VCC and 50Ω
connections.
3. Connections between the 10/100 IC and the
SMT connector should be direct (ideally no change
in direction) and of minimum length.
2. Connections to ground should be as short as possible.
