What is DP83848?
What is DP83848?
DP83848-EP ACTIVE The DP83848-EP was designed to allow Ethernet connectivity in the harshest environments. Our device meets IEEE 802.3u standards over a military temperature range of –55°C to 125°C. This device is ideally suited for harsh environments for example avionics, defense and industrial control applications.
What is RMII in Ethernet?
The Ethernet standard (IEEE 802.3u) defines the MII with 16 pins per port for data and control (8 data and 8 control). The RMII specification reduces the data interfaces from 4-bit (nibble) data to 2-bit (di-bit) data. In addition control is reduced to 3 signals (one of which is optional) and one clock).
What is the difference between MII and RMII?
RMII requires a 50 MHz clock where MII requires a 25 MHz clock and data is clocked out two bits at a time vs 4 bits at a time for MII or 1 bit at a time for SNI (10 Mbit/s only).
What is the difference between MAC and PHY?
The PHY layer defines the physical and electrical characteristics of the network. It is responsible for managing the hardware that modulates and demodulates the RF bits. The MAC layer is responsible for sending and receiving RF frames.
