CAMARILLO, Calif.--()--Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, announced that its advanced portfolio of 12G UHD-SDI products has set a new industry cable-reach performance benchmark utilizing a new coaxial cable optimized for UHDTV applications from Canare, a leading industry supplier of UHDTV cabling solutions.

Semtech’s 12G GS12141 retiming cable equalizer and GS12181 retiming cable driver each offer superior performance at all data rates and have established an industry benchmark for cable reach that is further enhanced when utilizing Canare’s L-5.5CUHD cable.

“The rapid industry adoption of UHDTV is placing greater demands on the performance of UHD-SDI infrastructures,” said Don Shaver, Director of Video Marketing for Semtech’s Signal Integrity Product Group. “Semtech and Canare share a common commitment to pushing the limits of UHDTV technology. Our range of 12G UHD-SDI interface products feature the industry’s most robust cable reach performance and excellent cross-talk and noise immunity, further augmented by Canare’s L-5.5CUHD cable. We are very pleased to see Canare addressing the critical requirements of broadcasters as they deploy their next generation UHD-SDI infrastructures.”

Semtech’s comprehensive portfolio of 12G UHD-SDI products is being demonstrated in Semtech’s booth N5024 at the National Association of Broadcasters (NAB) show on April 18-21 at the Las Vegas Convention Center.

Semtech’s UHD-SDI products feature ultra-low power consumption and provide industry-leading performance at 12Gbps rates. UHD-SDI is ideal for UHDTV infrastructures, including routers, cameras, monitors, switchers and more. It offers pristine image quality, is backwards compatible with existing SDI systems and is standardized by both the Society of Motion Picture and Television Engineers (SMPTE) and the International Telecommunication Union (ITU), simplifying UHDTV infrastructure upgrades and reducing risk for broadcasters.

Key Features of the GS12141 & GS12181

  • Multi-standard operation: 1Mb/s to 11.88Gb/s for increased design flexibility and a wider range of end-product applications
  • Performance optimized: For 11.88Gb/s with ultra-long cable reach, enabling designs that offer maximum performance at all data rates (GS12141). Ultra-low additive jitter for increased PCB design margin and class-leading output return loss performance that surpasses SMPTE specifications at all rates, simplifying board optimization, speeding time to market (GS12181)
  • Ultra-low power consumption: Ideal for multi-channel high density designs to minimize overall power consumption
  • Advanced feature set: Output pre-emphasis for compensating for long PCB trace lengths, simplifying PCB optimization (GS12141) and input trace equalization to compensate for long input trace lengths, critical for optimizing performance in 12G UHD-SDI designs (GS12181)

Key Features of the L-5.5CUHD cable

  • Design: Careful selection and a blend of materials was utilized to ensure high quality and long transmission distances.
  • Cable Size: The outside diameter of the cable is the same as existing L-5CFB and L-5CHD cable to ensure interoperability.
  • Performance: Transmission distances of greater than 100m are possible with 12G SDI signals.
  • Dedicated connector: To further enhance return loss performance with SMPTE ST 2082-1, a new BNC connector is also available.


The GS12141 and GS12181 are available now, and the GS12070 will be available in the second half of 2016. Semtech offers comprehensive design assistance, including field- and factory-based support. Data sheets, volume pricing and delivery quotes, as well as evaluation kits and samples, are available at
