Frequently Asked Questions
What is the operating temperature range of the DP83849IVS?
The DP83849IVS is rated for an industrial temperature range of -40°C to +85°C, making it suitable for demanding environments such as factory floors, outdoor equipment, and transportation systems where standard commercial-grade ICs would be unreliable.
How many Ethernet ports does the DP83849IVS support?
The DP83849IVS integrates two independent 10/100 Mbps Fast Ethernet PHY transceivers in a single package. Each port features its own MII or RMII interface, auto-negotiation, and cable diagnostics, enabling dual-port Ethernet without requiring two separate PHY ICs.
What interface does the DP83849IVS use to connect to a MAC or microcontroller?
The DP83849IVS supports both the standard Media Independent Interface (MII) and the Reduced MII (RMII) interface, allowing it to connect directly to most Ethernet MACs, FPGAs, or microcontrollers that implement either interface standard.
What package does the DP83849IVS come in?
The DP83849IVS is available in an 80-pin Thin Quad Flat Pack (TQFP) package (JESD-30 code S-PQFP-G80), offering a compact footprint suitable for space-constrained PCB designs in industrial and embedded networking applications.
