New miniature connector simplifies PCB layout reducing labour and assembly time

Hirose has developed a serial digital interface (SDI) compliant connector that supports high transmission speeds up to 12Gbps. The miniature BNC75 Series radio frequency (RF) connector features an optimized center contact design that simplifies PCB layout and supports SMT processing, decreasing labor and assembly time.   The connector supports 3G, 6G and 12G transmission, and is available in thread-fastened and bulkhead versions. By supporting high-speed transmissions up to 12Gbps versus traditional SDI connectors, the series can reduce the number of 3Gbps or 6Gbps SDI connectors required in a design. This not only enables a drastic reduction in the size of a device, but also significantly decreases mating time and component costs.   The series helps reduce the size of broadcasting cameras, FA/commercial cameras, security cameras, medical equipment, and more. It meets the 12G-SDI connector standard, offering high frequency performance that exceeds requirements up to the third harmonics (18GHz). The connector has a taper-shape single terminal design that generates high impedance matching performance at 75ohms. The single terminal design minimizes signal reflection and improves frequency characteristics versus through hole technologies. The ROHS certified connector has an operating temperature of -40C to +85C.   "The new BNC75 series supports image data transmission equivalent to 12Gbps through a single line specified in the 12G-SDI standard. A unique terminal design offers higher frequency performance by eliminating impedance disruptions often found in existing technologies," said Rick van Weezel, vice-president of sales and marketing for Hirose Electric USA.
