22 / 92 page  Intel ® LXT972M Single-Port 10/100 Mbps PHY Transceiver 22 Datasheet Document Number: 302875-005 Revision Date: 27-Oct-2005 5.1 Device Overview The LXT972M Transceiver is a single-port Fast Ethernet 10/100 transceiver that supports 10 Mbps and 100 Mbps networks. It complies with applicable requirements of IEEE 802.3. It directly drives either a 100BASE-TX line or a 10BASE-T line. 5.1.1 Comprehensive Functionality The LXT972M Transceiver provides a standard Media Independent Interface (MII) for 10/100 MACs. The LXT972M Transceiver performs all functions of the Physical Coding Sublayer (PCS) and Physical Media Attachment (PMA) sublayer as defined in the IEEE 802.3 100BASE-X standard. It also performs all functions of the Physical Media Dependent (PMD) sublayer for 100BASE-TX connections. If the LXT972M Transceiver is not set for forced operation, it uses auto-negotiation/parallel detection to automatically determine line operating conditions. If the PHY device on the other side of the link supports auto-negotiation, the LXT972M Transceiver auto-negotiates with it using Fast Link Pulse (FLP) Bursts. If the PHY partner does not support auto-negotiation, the LXT972M Transceiver automatically detects the presence of either link pulses (10 Mbps PHY) or Idle symbols (100 Mbps PHY) and sets its operating conditions accordingly. The LXT972M Transceiver provides half-duplex and full-duplex operation at 100 Mbps and 10 Mbps. 5.1.2 Optimal Signal Processing Architecture The LXT972M Transceiver incorporates high-efficiency Optimal Signal Processing (OSP) design techniques, which combine optimal properties of digital and analog signal processing. The receiver utilizes decision feedback equalization to increase noise and cross-talk immunity by as much as 3 dB over an ideal all-analog equalizer. Using OSP mixed-signal processing techniques in the receive equalizer avoids the quantization noise and calculation truncation errors found in traditional DSP-based receivers (typically complex DSP engines with A/D converters). This results in improved receiver noise and cross-talk performance. The OSP signal processing scheme also requires substantially less computational logic than traditional DSP-based designs. This lowers power consumption and also reduces the logic switching noise generated by DSP engines. This logic switching noise can be a considerable source of EMI generated on the device’s power supplies. The OSP-based LXT972M Transceiver provides improved data recovery, EMI performance, and low power consumption. |
