Hirose Electric — D-FL75 Series Connectors

The D.FL75 series from Hirose are 75 Ω surface-mount connectors which provide the high-speed capability required for 12G-SDI signal applications. 

The 12G-SDI standard was specified by the Society of Motion Picture and Television Engineers (SMPTE) in response to the need for higher transmission speeds in broadcasting equipment. The standard is the TV and film industry’s response to demand for content in higher definition, first 4K and now 8K.  

The SMPTE 12G-SDI standard is used for transmissions between broadcast cameras and other equipment. The D.FL75 series connectors conform to the specifications of the standard. 

These Hirose connectors fit in space-constrained board designs: they require mounting space of just 4 mm x 4 mm, and their mated height is 2.9 mm maximum. This space-saving design gives the designer the freedom to configure board layouts that contain multiple high-density interfaces, including those with a narrow pitch, as well as multi-stage arrangements.  

The D.FL75 connectors are terminated with an ultra-fine coaxial cable rated for signal frequencies of up to 12 GHz. The D.FL75 supports automatic mounting, and enables easy mating. A clear tactile click sounds when the connector is fully mated to assure the assembler of a complete electrical and mechanical connection.
