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.
## Technical Specifications
• **Switching Architecture:** True non-blocking, store-and-forward with pause frame support
• **Chipset:** Marvell 88E6060 with high-speed address lookup engine
• **Frame Buffer:** 512 kb on-chip port map memory with embedded frame buffer
• **Port Count:** 5 × 10/100 Mbps auto-crossover Ethernet ports
• **MAC Controllers:** Fully independent per port
• **Standards Compliance:** IEEE 802.3 and IEEE 802.3u
• **Form Factor:** PC/104 (16-bit ISA bus interface)
• **Power Supply:** +5VDC @ 0.44 A maximum (2.2 W typical)
## Key Features
• Auto-negotiation and speed auto-sensing for plug-and-play operation
• Auto-MDI/MDIX and auto-polarity support eliminate crossover cable requirements
• Bridge loop prevention
• VLAN capability with port-based, field-programmable configuration stored in onboard memory
• RS-232 serial interface for VLAN settings via ParVLAN software
• Any port operates as uplink or standard connection
• Standalone or PC/104 bus-integrated deployment modes
## Connectivity Options
Onboard RJ-45 jacks pair with 4-pin locking Molex headers for embedded integration, or optional faceplate/endcap RJ-45 connectivity via separate cable sets. External +5VDC power input available through 2-pin Molex power header or PC/104 bus supply.
## Typical Applications
Aviation, military, industrial, and transportation systems requiring deterministic, low-latency switching in space-constrained environments. Qualified to MIL-STD-810 environmental standards for harsh-condition deployments.
**Note:** PRV-1059 series production has reached end-of-life status. Limited inventory available on first-come, first-served basis.
