Curtiss-Wright / Parvus PRV-1059-22 5-Port PC/104 10/100 Fast Ethernet Switch

The Curtiss-Wright/Parvus PRV-1059-22 is a 5-port PC/104 Fast Ethernet switch delivering non-blocking, store-and-forward switching fabric for embedded network applications. Built on the Marvell 88E6060 chipset with fully independent media access controllers, it supports 10/100 Mbps speeds across five auto-crossover RJ-45 ports with configurable Molex header connectivity options. The unit operates from +5VDC input at 2.2 W maximum power consumption (0.44 A) and qualifies to IEEE 802.3/802.3u standards.
