MACOM announces first analog CDR-based PAM-4 portfolio, targeting compliance with Open Eye MSA

MACOM Technology Solutions Holdings Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for RF, microwave, millimeter-wave and lightwave applications) has announced a complete analog 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).

Optimized for volume-scale deployment in high-density cloud data-center links, MACOM’s new components aim to enable faster, lower-cost and more power-efficient optical modules. as defined by the upcoming Open Eye MSA industry standard.

MACOM’s end-to-end transmit and receive portfolio features low-cost, low-power extensions to its existing lineup of clock & data recovery (CDRs), drivers and transimpedance amplifiers (TIAs), adding a companion integrated 200G FR4 L-PIC (photonic integrated circuit with integrated lasers) optimized to reduce module costs through improved ease of assembly, calibration and test. These components are designed to eliminate the need for expensive, power-hungry signal processing and 53Gbps externally modulated lasers (EMLs), enabling streamlined optical module architectures targeted at 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, a MATA-03819 quad TIA, MACOM BSP56B photodetectors and the MASC-38040 four-channel receive PAM-4 CDR. This approach is expected to deliver over 25% reduction in power consumption while simultaneously driving the cost per gigabit down compared with existing CWDM4 and digital signal processing (DSP)-based PAM-4 solutions. Cloud customers can now double their link rate with only minor, incremental power and cost.

“MACOM is proud to be part of an ecosystem that enables seamless component interoperability among a broad group of industry-leading technology providers, including providers of electronics, lasers and optical components,” says Preet Virk, senior VP & general manager, Networks. “MACOM is committed to enabling the Open Eye MSA’s charter, in part by leveraging our comprehensive portfolio of high-performance analog components and L-PICs to help customers achieve optimal performance, power efficiency and cost structures,” he adds. “Our extensive application expertise and industry leadership in PAM-4 enabling technologies will help to ensure a seamless migration from 100G CWDM4 to industry-standard 200G and 400G PAM-4 module architectures,” he believes.

The Open Eye MSA group aims to accelerate the adoption of data-center interconnects scaling to 50Gbps, 100Gbps, 200Gbps and 400Gbps by expanding existing standards to enable optical module implementations using multiple technologies including optimized CDR-based architectures in addition to existing DSP architectures.

All of the MACOM products highlighted in this CDR and LPIC-based portfolio are sampling to customers now.
