Evertz DIN1.0/2.3 Connector Details
As I/O density increases and size decreases today’s broadcast manufactures are constantly looking for
ways to find a happy medium between these two diametrically opposed concepts. One simple way is to
move away from standard 75Ω BNC connectors and to begin using some smaller form factor 75 Ω
connector. Recent developments from connector manufactures has resulted in the availability of a new
type of connector quickly becoming popular to meet exactly this need. The connector is referred to as a
DIN type connector. Sometimes mistakenly referred to as MiniDIN, Mini BNC or SMA connectors DIN
type 75 Ω connectors are becoming very popular both due to their high performance capability, easily
supporting 3G applications, their obvious high density, and the fact that the connector offers a positive
locking style connector instead of BNC’s compression style fit. Evertz’s next generation of smaller high
density applications must not only work well in terms of performance and signal quality. They must also
support 3Gb/s signals, work well in difficult physical environments such as Trucks and OB vans. That is
why for applications requiring a connector with a higher density than that of BNC while offering 3Gb/s
performance and a positive lock onto their mating jack Evertz has chosen to use the DIN connector.
The particular connector chosen is the DIN1.0/2.3 connector. This connector, originally established as a
50 Ω connector for the telecommunications industry, has been redesigned as a 75 Ω connector for the
broadcast industry. The connectors are typically rated to 3.7-4Gb/s data rates (a 4Gb/s capable
connector might be referred to as a 2GHz connector) and support typical mini hi-res cable or standard
HD/3G cable depending on the connector.
For small diameter cable, Belden 1855A is the cable Evertz uses as a reference, but of course any
cable with appropriately matching specifications to that of Belden 1855A cable will work. When
choosing a different cable take care to compare the AWG/diameter of the center conductor, the OD
(outside diameter) of the outer shield, and the OD of the jacket (total cable OD), as the measurements
that should be carefully matched to ensure the cable will properly perform with the DIN1.0/2.3
connectors that support this size cable. Information on 1855A style connector is included below.
For large diameter cable, Belden 1694A is the cable Evertz uses as a reference but of course any cable
with appropriately matching specifications to that of Belden 1694A cable will work. Information on
1694A style connectors is included below. There are several other types of connectors available from
different manufacturers, which meet the DIN1.0/2.3 specification, and these connectors will work too.
We offer this information on 3rd party connectors as a result of empirical anecdotal testing and not as
an endorsement of one vendor over another. Please contact Evertz for further support and information
regarding DIN Specifications.
