Download the PM8379 datasheet PDF. This datasheet also covers the PM8379_PMC variant, as both devices belong to the same 20-port 4.25 gbit/s fc-al cut-through switch family and are provided as variant models within a single manufacturer datasheet.

Key Features

that significantly increase total system availability, reliability, and serviceability.
Built-in self test capability with FC Frame Generator/Comparator.
Supports a 106.25 MHz, 40-bit (20 receive + 20 transmit) DDR parallel interface that acts as a 21st port. This flexible interface enables external functions such as enclosure management or other user-proprietary functions to be implemented using a low cost FPGA. CUT-.

PM8379 CTS 20x4G Advance 20-Port 4.25 Gbit/s FC-AL Cut-Through Switch The CTS 20x4G is designed to interface directly to Fibre Channel disk drives in a storage array. It can interface directly to optics or to cables at the ingress/egress www.datasheet4u.com point of an enclosure and is able to determine if an incoming frame is destined for a drive within that enclosure. After determining which port is associated with the frames recipient, a cut through operation to that port is performed thereby significantly reducing system latency and improving performance. The CTS 20x4G provides unique disk isolation features that significantly increase total system availability, reliability, and serviceability. • Built-in self test capability with FC Frame Generator/Comparator. • Supports a 106.
