88E1543-A1-LKJ2C000 Description

Short technical summary and product information.

The 88E1543-A1-LKJ2C000 is a quad-port 10/100/1000 BASE-T PHY transceiver from Marvell, part of the Alaska Gigabit Ethernet family. It integrates four independent Ethernet transceivers supporting IEEE 802.3 protocols and includes an SGMII interface for connection to a MAC. The device operates in both full and half duplex modes at data rates of 10 Mbps, 100 Mbps, and 1 Gbps.

 

Power is supplied via three separate rails: a 1.8V core supply (1.71V to 1.89V), a 2.5V I/O supply (2.38V to 2.63V), and a 3.3V analog supply (3.13V to 3.47V). The receiver includes 360 mV of hysteresis for improved noise immunity. The transceiver also supports IEEE 1149.1 JTAG boundary scan for testing.

 

The device is housed in a 128-lead LQFP with an exposed pad (14x20 mm) for enhanced thermal dissipation. It is designed for surface mount assembly and operates over a commercial temperature range of 0°C to 70°C. Typical applications include Ethernet switches, routers, network interface cards, and media converters.
