BCM5338MKQM

Product Summary

The BCM5338MKQM is a sixth-generation switch designed based on the field-proven industry-leaders, the BCM5328 and BCM5328M switches. This device combines all of the functions of a high-speed switch system—including packet buffers, PHY transceivers, MACs, address management, and a non-blocking switch fabric into a single 0.18-micron CMOS device. The BCM5338MKQM complies with IEEE 802.3, IEEE 802.3u, and IEEE 802.3x specifications, including the MAC control PAUSE frame and auto-negotiation subsections, providing compatibility with all industry-standard Ethernet and Fast Ethernet devices.
