Frequently Asked Questions
What temperature range does the DP83848I support and why does that matter for industrial designs?
The DP83848I is rated for -40°C to 85°C, covering the full industrial temperature range. This makes it suitable for factory floors, outdoor enclosures, and automotive auxiliary electronics where ambient temperatures exceed the 0°C to 70°C commercial range.
Which data rate and host interface does the DP83848I use to connect to a microcontroller?
The DP83848I operates at 10 Mbps or 100 Mbps with auto-negotiation and connects to the host via a standard MII interface, making it directly compatible with Ethernet MAC controllers integrated in devices like the LM3S series, STM32, and similar MCUs.
How many Ethernet ports does the DP83848I support and what supply voltage does it require?
The DP83848I supports 1 Ethernet port and operates from a single 3.3 V supply, reducing bill-of-materials complexity by eliminating separate voltage regulators for a 5 V or 1.8 V rail.
What package does the DP83848I use and how does that affect PCB routing for high-speed Ethernet signals?
The DP83848I comes in a 48-pin PQFP package with a low-profile fine-pitch flatpack style, allowing relatively compact placement while keeping differential pair traces short, which simplifies 100 Mbps signal integrity on a 4-layer PCB.
