1.0 Introduction
This document is applicable to the Intel® 82562V 10/100 Mbps Platform LAN Connect device.
1.1 Overview
The Intel® 82562V 10/100 Mbps Platform LAN Connect is a highly-integrated device designed for 10 or 100 Mbps Ethernet systems. It is based on the IEEE 10BASE-T and 100BASE-TX standards. The IEEE 802.3u standard for 100BASE-TX defines networking over two pairs of Category 5 unshielded twisted pair cable or Type 1 shielded twisted pair cable. The 82562V complies with the IEEE 802.3u Auto-Negotiation standard and the IEEE 802.3x Full Duplex Flow Control standard. The 82562V also includes a PHY interface compliant to the current platform LAN connect interface.

Unshielded Twisted Pair (UTP) or Shielded Twisted Pair (STP) wire. code. Table 5 lists the 4B/5B encoding scheme associated with the given symbol. Table 5. 4B/5B Encoder
Networking Silicon — 82562V Datasheet 13 5.1.1.2 100BASE-TX Scrambler and MLT-3 Encoder Data is scrambled in 100BASE-TX in order to reduce electromagnetic emissions during long transmissions of high-frequency data codes. The scrambler logic accepts 5 bits from the 4B/5B encoder block and presents the scrambled data to the MLT-3 encoder. The 82562V implements the 11-bit stream cipher scrambler as adopted by the ANSI XT3T9.5 committee for UTP operation. The cipher equation used is: X[n] = X[n-11] + X[n-9] (mod 2) The MLT-3 encoder receives the scrambled Non-Return to Zero (NRZ) data stream from the scrambler and encodes the stream into MLT-3 for presentation to the driver. MLT-3 is similar to NRZ1 coding, but three levels are output instead of two. The three output levels are positive, negative and zero. When an NRZ “0” arrives at the input of the encoder, the last output level is maintained (either positive, negative or zero). When an NRZ “1” arrives at the input of the encoder, the output steps to the next level. The order of steps is negative-zero-positive-zero which continues periodically. Refer to IEEE 802.3 Specification for details. 5.1.1.3 100BASE-TX Transmit Framing The 82562V does not differentiate between the fields of the MAC frame containing preamble, start of frame delimiter, data and Cyclic Redundancy Check (CRC). The 82562V encodes the first byte of the preamble as the “JK” symbol, encodes all other pieces of data according to the 4B/5B lookup table, and adds the “TR” code after the end of the packet. The 82562V scrambles and serializes the data into a 125 Mbps stream, encodes it as MLT-3, and drives it onto the wire.

5.1.2.3 MLT-3 Decoder, Descrambler, and Receive Digital Section
Networking Silicon — 82562V Datasheet 15 In 100BASE-TX mode, the 82562V can detect errors in receive data in a number of ways. Any of the following conditions is considered an error:
- Link integrity fails in the middle of frame reception.
- The start of stream delimiter “JK” symbol is not fully detected after idle.
- An invalid symbol is detected at the 4B/5B decoder.
- Idle is detected in the middle of a frame (before “TR” is detected). 5.2 10BASE-T Mode 5.2.1 10BASE-T Transmit Blocks 5.2.1.1 10BASE-T Manchester Encoder After the 2.5 MHz clocked data is serialized in a 10 Mbps serial stream, the 20 MHz clock performs the Manchester encoding. The Manchester code always has a mid-bit transition. The boundary transition occurs only when the data is the same from bit to bit. For example, if the value is 11b, then the change is from low to high within the boundary. 5.2.1.2 10BASE-T Driver and Filter Since 10BASE-T and 100BASE-TX have different filtration needs, both filters are implemented inside the chip. The 82562V supports both technologies through one pair of transmit differential pins and by externally sharing the same magnetics. In 10 Mbps mode the line drivers use a pre-distortion algorithm to improve jitter tolerance. The line drivers reduce their drive level during the second half of “wide” (100 ns) Manchester pulses and maintain a full drive level during all narrow (50 ns) pulses and the first half of the wide pulses. This reduces line overcharging during wide pulses, a major source of jitter. 5.2.2 10BASE-T Receive Blocks 5.2.2.1 10BASE-T Manchester Decoder The 82562V performs Manchester decoding and timing recovery in 10BASE-T mode. The Manchester encoded data stream is decoded from the receive differential pair. This data is transferred to the controller at 2.5 MHz/nibble. The high-performance circuitry of the 82562V exceeds the IEEE 802.3 jitter requirements. 5.2.2.2 10BASE-T Twisted Pair Ethernet (TPE) Receive Buffer and Filter In 10 Mbps mode, data is expected to be received on the receive differential pair after passing through isolation transformers. The filter is implemented inside the 82562V for supporting single magnetics that are shared with the 100BASE-TX side. The input differential voltage range for the Twisted Pair Ethernet (TPE) receiver is greater than 585 mV and less than 3.1 V . The TPE receive buffer distinguishes valid receive data, link test pulses, and the idle condition, according to the requirements of the 10BASE-T standard. The following line activity is determined to be inactive and is rejected as invalid data:
16 Datasheet
- Differential pulses of peak magnitude less than 300 mV .
- Continuous sinusoids with a differential amplitude less than 6.2 VPP and frequency less than 2 MHz.
- Sine waves of a single cycle duration starting with 0° or 180° phase that have a differential amplitude less than 6.2 VPP and a frequency of at least 2 MHz and not more than 16 MHz. These single-cycle sine waves are discarded only if they are preceded by 4 bit times (400 ns) of silence. All other activity is determined to be either data, link test pulses, Auto-Negotiation fast link pulses, or the idle condition.
