MOLEX 73171

BNC 75 Ohm Connectors
FEATURES AND SPECIFICATIONS
73171
Molex offers a full line of BNC 75 Ohm connectors and cables to meet and exceed the serial-data, transmission-performance requirements of
High-Definition TV (HDTV)
The demand for HDTV products is transforming
the broadcast-television market and its current
hardware infrastructure. The ongoing standards
conversions from the Society of Motion Picture
Television Engineers (SMPTE) 292M (HD-SDI -1.5
Gbps) to SMPTE 424M (3G-HD-3.0 Gbps) demand a
previously unrivaled attention to hardware design
detail; proper operation and signal integrity must be
ensured throughout the entire broadcast-transmission
line. Passive connectors and coaxial cabling
encompass a significant portion of a typical broadcast
transmission line. Molex offers a full line of BNC 75
Ohm connectors and cables, designed to exceed the
serial data transmission performance requirements of
SMPTE 424M (3G-HD).
Molex BNC 75 Ohm connectors yield Return Loss
performance that exceeds industry standard
requirements of SMPTE 424M and allows for sizeable
future bandwidth expansion without connector
hardware changes. BNC 75 Ohm connectors transmit
signals at 3.0 GHz, ensuring performance standards
are met and signal integrity is not compromised.
Molex also offers 75 Ohm 1.0/2.3 GHz connectors
to address the mobile broadcast-truck market, where
truck-weight reduction is paramount. The 1.0/2.3
connectors and cables also exceed the Return Loss
performance requirements of SMPTE424M. Molex
provides 75 Ohm connector and cable assembly
solutions to fulfill the current performance challenges
of the broadcast television/video industry.
In addition to the 75 Ohm, 3.0 GHz+ connectors
(Series 73171) designed for HDTV applications,
Molex offers BNC connectors in both 50 and 75
Ohm impedance levels (multiple series numbers)
for applications including telecommunications,
video, audio and test equipment. All BNC connectors
are miniature, lightweight and weatherproof. The
double-stud, bayonet-coupling design of the BNC
connector yields an easy-to-use, quick-connecting and
disconnecting device that accounts for its popularity.
BNC connectors are manufactured to MIL-PRF-39012
requirements and are typically used in applications
operating up to 4 GHz. Mini-BNC 75 Ohm connectors
are also available and are 25 to 30% smaller than
traditional BNC designs.
n 75 Ohm cable assemblies and mating plugs are
also available for a complete Molex solution
