Microchip Technology, Inc. Interface - Drivers, Receivers, Transceivers LAN8742A-CZ

The LAN8742A-CZ is a single-chip Ethernet physical layer transceiver designed for 10/100 Mbps applications, compliant with IEEE 802.3/802.3u standards. It features a compact 24-pin VQFN package, measuring 4 x 4 mm, and is RoHS-compliant. The device supports RMII interface, cable diagnostics, and Wake on LAN (WoL) functionality, making it suitable for various applications including set-top boxes, networked printers, and embedded telecom systems. This transceiver incorporates flexPWR technology, allowing for flexible power management with a variable I/O voltage range from 1.8 V to 3.3 V, and includes an integrated 1.2 V regulator. It also supports HP Auto-MDIX, automatic polarity detection, and correction, as well as loop-back modes for testing. The LAN8742A-CZ operates within a commercial temperature range of 0¬8C to +70¬8C, with an industrial variant available for -40¬8C to +85¬8C. Engineers considering this product will find it advantageous for low power consumption applications, as it offers various low power modes and can operate with a single 3.3 V supply. The ability to use a low-cost 25 MHz crystal further reduces the bill of materials (BOM) costs.
