APPLICATION Case

MACOM Technology Solutions Inc. has launched a pair of analog semiconductors at OFC 2021 designed to support 200G and 400G short reach module designs for multimode fiber data center network requirements. The devices, applicable to QSFP, OSFP, and QSFP-DD transceivers and active optical cable, offers bit error rate performance that exceeds IEEE standard specifications and is compliant with Open Eye MSA eye mask specifications, the company adds.

MACOM offers analog chips for 200G, 400G multimode fiber data center networks

The analog chip offering pairs the MATA-38044, a 4x56-Gbps PAM4 CDR and TIA device, with the MALD-38045, a 4x56-Gbps PAM4 CDR and VCSEL driver. The MATA-38044 is a four-channel, 28-GBaud linear PAM4/NRZ TIA with automatic gain control and integrated CDRs. The MALD-38045 is a four-channel 28-GBaud PAM4/NRZ VCSEL driver with an integrated CDR; it directly modulates VCSELs in the transmit path. Each of the four channels can operate independently. Both devices feature what MACOM asserts is “industry leading low power” and can operate at Ethernet, Fibre Channel, and InfiniBand PAM4 and NRZ data rates up to 56 Gbps.


The analog devices are offered as an alternative to DSP-based optical module designs. The analog approach offers reduced power consumption, latency, cost, and footprint, MACOM asserts.
