KSZ9567R 1.0 PREFACE 1.1 Glossary of Terms TABLE 1-1: GENERAL TERMS Term Description 10BASE-Te
10 Mbps Ethernet, 2.5V signaling, IEEE 802.3 compliant
100BASE-TX
100 Mbps Fast Ethernet, IEEE 802.3u compliant
1000BASE-T
1000 Mbps Gigabit Ethernet, IEEE 802.3ab compliant
ADC
Analog-to-Digital Converter
AN
Auto-Negotiation
AVB
Audio Video Bridging (IEEE 802.1BA, 802.1AS, 802.1Qat, 802.1Qav)
BLW
Baseline Wander
BPDU
Bridge Protocol Data Unit. Messages which carry the Spanning Tree Protocol informa- tion.
Byte
8 bits
CRC
Cyclic Redundancy Check. A common technique for detection data transmission errors. CRC for Ethernet is 32 bits long.
CSR
Control and Status Registers
DA
Destination Address
DWORD
32 bits
FCS
Frame Check Sequence. The extra checksum characters added to the end of an Ethernet frame, used for error detection and correction.
FID
Frame or Filter ID. Specifies the frame identifier. Alternately is the filter identifier.
FIFO
First In First Out buffer
FSM
Finite State Machine
GPIO
General Purpose I/O
Host
External system (Includes processor, application software, etc.)
IGMP
Internet Group Management Protocol. Defined by RFC 1112, RFC 2236, and RFC 4604 to establish multicast group membership in IPv4 networks.
IPG
Inter-Packet Gap. A time delay between successive data packets mandated by the network standard for protocol reasons.
Jumbo Packet
A packet larger than the standard Ethernet packet (1518 bytes). Large packet sizes allow for more efficient use of bandwidth, lower overhead, less processing, etc..
lsb
Least Significant Bit
LSB
Least Significant Byte
MAC
Media Access Controller. A functional block responsible for implementing the media access control layer, which is a sublayer of the data link layer.
MDI
Medium Dependent Interface. An Ethernet port connection that allows network hubs or switches to connect to other hubs or switches without a nul -modem, or crossover, cable.
MDIX
Media Independent Interface with Crossover. An Ethernet port connection that allows networked end stations (i.e., PCs or workstations) to connect to each other using a null-modem, or crossover, cable.
MIB
Management Information Base. The MIB comprises the management portion of net- work devices. This can include monitoring traffic levels and faults (statistical), and can also change operating parameters in network nodes (static forwarding addresses).
MII
Media Independent Interface. The MII accesses PHY registers as defined in the IEEE 802.3 specification. DS00002329D-page 4  2017-2019 Microchip Technology Inc.
