Cable Modulators

Market drivers and technology advancements have changed what we expect from Cable modulators. Calian, Advanced Technologies develops market-leading Cable QAM and DOCSIS 3.1 OFDM modulator solutions to address the most challenging technical requirements or to meet cost-effective market needs.

Our solutions offer individually agile ITU-T J.83 Annex A, B, and C QAM carriers throughout the RF band with RF performance that exceeds DRFI specifications.

Calian, Advanced Technologies also offers DOCSIS 3.1 OFDM modulator designs that meet the DOCSIS specifications including the DOCSIS 3.1 convergence layer. We can provide you with Cable modulators solutions that have MER performance above 50dB, and we can provide you Cable modulators that address cost-sensitive market applications.

We supply the product as commercial off the shelf modulators, custom-designed modules, cards, or finished products. And if you are looking to undertake a development yourself, we can also support you with a reference design or FPGA logic core.


Calian, Advanced Technologies is a Xilinx Alliance Partner and can support your internal DOCSIS 3.1 and SC-QAM (ITU J.83) Cable modulator design needs.

Our logic architectures for SC-QAM are for Xilinx 6 series, 7 series, and UltraScale FPGAs. DOCSIS 3.1 logic architectures are designed on and for Xilinx 7 series and UltraScale FPGAs.

Our IP has support for many commercially available DAC silicon products. We are available to provide reference design materials for a complete solution, design services to support your design efforts, or an FPGA logic core offering high-density SC-QAM (ITU J.83) and DOCSIS 3.1 OFDM digital modulation.
