MACOM Technology Solutions Inc., a leading semiconductor supplier, has announced the availability of its latest copper connectivity solution - the MACD-41804 Cable Driver with Equalizer. Designed to enable low power, high density copper interconnects for next generation scale-up applications, the new product complements MACOM's existing portfolio of multi-channel equalizer devices and offers enhanced performance and flexibility.

Why it matters

MACOM's new cable driver solution can enable customers to increase data transmission throughput while maintaining the benefits of copper, including lower power consumption and cost compared to optical interconnects. This is particularly important for scale-up applications that require high-performance, energy-efficient connectivity.

The details

The MACD-41804 integrates input equalization, broad dynamic range, optional gain adaptation and mission mode diagnostics. It is tailored for cost and power efficient links across a variety of form factors including 1.6T OSFP. The addition of gain adaptation and associated diagnostics features provides users with enhanced link capabilities as well as monitoring feedback, translating to power and cost-efficient copper connectivity. The solution is available in bumped die used in compact flip-chip packaging, supporting high volume manufacturing.
