• Manufacturer Part Number: NE8392C
• Description: Coaxial Transceiver Interface For Ethernet/thin Ethernet
• Manufacturer: NXP Semiconductors

1. Currents flowing into device pins are positive. All voltages are referenced to ground unless otherwise specified. For ease of interpretation,
2. All typicals are for V
3. I
4. The TXO pin shall continue to sink at least I
5. Collision threshold for an AC signal is within 10% of V
6. Measured on secondary side of isolation transformer (see Connection Diagram, Figure 1). The transformer has a 1:1 turns ratio with an
7. Measured as the voltage difference between the RX pins or the CD pins with the transformer removed.
