10/100 BASE-T SINGLE PORT
TRANSFORMER MODULES
1:1 Transmit Turns Ratios Compatible with
Broadcom, ICS, Intel, Kendin, Level One, Lucent,
National Semiconductor, SEEQ and TDK Transceivers
This line of 10/100Base-TX 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-5). The modules 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. Additionally, each solution
meets the stringent open circuit inductance requirements
imposed by IEEE. When an 8 mA DC current is applied across
the transformer windings, the transformer will provide at least
350 µH. The transformers used in each module also provide
1500 Vrms minimum isolation, wide band width with minimal
attenuation and fast rise times to minimize system level jitter.
The H1086 provides a slower rise time for use with National’s
DP83843. The H1117 pin out is optimized for Kendin’s
KS8731 and KS8732. The HX1148 and HX1178 provide an
extended temperature operating range (-40° to +85°C).
Surface mount devices manufactured by Pulse are designed
to meet all published specifications after exposure to surface
mount soldering temperatures. The SMT modules in this data
sheet are transfer-molded in IC style packaging, making them
robust enough to withstand convection and infrared reflow
solder temperatures of up to 235°C. Additionally, compliant
leads provide excellent solder-joint reliability with a coplanarity
of ±.002" (0,05 mm).
Application Notes
NOTE: Modules are packaged in tubes, unless Tape & Reel is specified. Please add the suffix “T” (such as H1012T) for Tape & Reel orders.
