Macom Announces analogue CDR-Based PAM-4 range
Portfolio targeted for compliance with the newly formed Open Eye MSA
Macom Technology has announced a complete analogue and silicon photonics portfolio for seamless integration in 50Gbps, 100Gbps, 200Gbps and 400Gbps optical modules targeted for compliance with the newly formed Open Eye Multi-Source Agreement (MSA) www.openeye-msa.org.
The components are optimised for volume-scale deployment in high-density cloud data centre links.
Macom’s transmit and receive portfolio features extensions to its existing lineup of Clock and Data Recovery (CDRs), drivers and (Transimpedance Amplifiers (TIAs), adding a companion integrated 200G FR4 L-PIC optimised to reduce customers’ module costs through improved ease of assembly, calibration and test. These components are said to eliminate the need for expensive, power-hungry signal processing and 53Gbps EMLs, enabling streamlined optical module architectures targeted for 200G and 400G connectivity.
Macom’s full CDR-based and L-PIC-based portfolio comprises the MAOM-38053 four-channel transmit PAM-4 CDR with an integrated driver, and an L-PIC transmitter and on the receive side, features a MATA-03819 quad TIA, Macom BSP56B photodetectors and the MASC-38040 four-channel receive PAM-4 CDR. This approach is anticipated to deliver over 25 percent reduction in power consumption while simultaneously driving the cost per gigabit down as compared to today’s CWDM4 and digital signal processing (DSP)-based PAM-4 solutions.
