The HX1188NL is a dual-port 10/100Base-T Ethernet LAN transformer designed to provide signal isolation, impedance matching, and noise suppression between a PHY chip and the network cable. It is commonly used in Fast Ethernet applications and supports standard IEEE 802.3 requirements for reliable data transmission.
The HX1188NL typically features a 1:1 turns ratio for both transmit and receive channels, an inductance of around 350 µH, and an isolation voltage of approximately 1500 Vrms. It is designed for 10/100Base-T Ethernet and comes in a compact surface-mount package suitable for PCB integration.
HX1188NL supports 10Base-T and 100Base-TX Ethernet data rates, making it suitable for Fast Ethernet applications. It does not support Gigabit Ethernet (1000Base-T), as its bandwidth and electrical characteristics are not designed for higher-speed signaling requirements.
No, HX1188NL is not compatible with Gigabit Ethernet because it is specifically designed for 10/100Base-T applications. Gigabit Ethernet requires different magnetics with higher bandwidth and stricter performance characteristics, so a dedicated 1000Base-T transformer should be used instead.
The HX1188NL typically has a 1:1 turns ratio for both transmit and receive channels, which ensures proper impedance matching between the Ethernet PHY and the twisted-pair cable. This ratio is standard for most 10/100Base-T LAN transformer designs.
HX1188NL provides an isolation voltage of approximately 1500 Vrms, which helps protect Ethernet devices from electrical surges and ground potential differences. This isolation is essential for meeting safety and reliability requirements in network equipment.
HX1188NL is typically compatible with 10/100Base-T Ethernet PHY chips such as Microchip LAN8720, TI DP83848, and similar Fast Ethernet transceivers. However, designers should always verify compatibility with the PHY manufacturer’s reference design to ensure optimal performance.
A common replacement for HX1188NL is the LP1188NL, which offers similar electrical characteristics, including 1:1 turns ratio and 10/100Base-T support. When selecting an equivalent, engineers should verify key parameters such as inductance, insertion loss, and isolation voltage.
HX1188NL is used between the Ethernet PHY and the RJ45 connector to provide isolation and signal conditioning. It is typically placed close to the PHY on the PCB, with proper center-tap biasing and controlled impedance routing to ensure signal integrity and EMI compliance.
HX1188NL is a discrete LAN transformer used on the PCB, while an RJ45 connector with integrated magnetics (MagJack) combines the transformer and connector into a single component. Discrete solutions offer more design flexibility, while integrated solutions simplify layout and assembly.
