57 / 92 page  Intel ® LXT972M Single-Port 10/100 Mbps PHY Transceiver Datasheet 57 Document Number: 302875-005 Revision Date: 27-Oct-2005 6.0 Application Information 6.1 Magnetics Information The LXT972M Transceiver requires a 1:1 ratio for both the receive and transmit transformers. The transformer isolation voltage should be rated at 2 kV to protect the circuitry from static voltages across the connectors and cables. For transformer/magnetics requirements, see Table 19. Note: Before committing to a specific component, contact the manufacturer for current product specifications and validate the magnetics for the specific application. 6.2 Typical Twisted-Pair Interface Table 20 provides a comparison of the RJ-45 connections for NIC and Switch applications in a typical twisted-pair interface setting. Table 19. Magnetics Requirements Parameter Min Nom Max Units Test Condition Rx turns ratio – 1 : 1 – – – Tx turns ratio – 1 : 1 – – – Insertion loss 0.0 0.6 1.1 dB – Primary inductance 350 – – μH– Transformer isolation – 1.5 – kV – Differential to common mode rejection 40 – – dB 0.1 to 60 MHz 35 – – dB 60 to 100 MHz Return Loss -16 – – dB 30 MHz -10 – – dB 80 MHz Table 20.
