MACOM releases 100-Gbps PAM4 DSP PHYs

Aug. 13, 2020
The PAM4 PHYs with integrated DSP, forward error correction (FEC), and multiplexing functionality are designed to enable single-wavelength 50- and 100-Gbps optical transceivers.

MACOM Technology Solutions Inc. has announced design completion and production release of its low-power CMOS digital signal processor (DSP)-based PAM4 physical layer devices (PHYs). The PAM4 PHYs with integrated DSP, forward error correction (FEC), and multiplexing functionality are designed to enable single-wavelength 50- and 100-Gbps optical transceivers. These devices also offer low latency, low power, and a small footprint package optimized for next-generation optical transceiver modules, MACOM asserts.

The integrated laser driver is suitable for direct connection to an optical modulator, avoiding the need for a discrete driver and reducing both cost and complexity. An onboard management processor simplifies module implementation, while the flexible DSP-based equalizer supports optical links up to and beyond 10 km over single-mode fiber.

Optional low-latency FEC enables IEEE-compliant link performance with both legacy and current-generation switch silicon. The product is well-suited for inside and outside data center applications, the company asserts. MACOM design and applications engineering teams are available to support immediate design-in activities.
