The IP1717BLF with Ethernet ICs LQFP-128 RoHS is a single chip integrated 10/100 Base-T media access controller (MAC) and 10/100 Base-T physical layer (PHY) transceiver designed for 100 Mb/s full and half-duplex operation in Local Area Network (LAN) applications. It is fabricated in low-voltage CMOS technology and operates from a single +2.5V/3.3V power supply. It is packaged in a 3.3V LQFP-128 RoHS package, making it suitable for a wide variety of applications with limited space. The IP1717BLF is designed with cutting-edge features including an advanced Address Lookup Engine (ALE) and a fast, accurate Priority Queue Engine (PQE). Moreover, the MAC utilizes address recognition schemes such as CRC error checking, half-duplex backoff, and auto-negotiation. The IP1717BLF also has integrated support for IEEE1588, an industry-standard high-precision time-stamping protocol. Furthermore, it is also compliant with IEEE 802.3 Ethernet, IEEE 802.3u 100Base-Tx specifications, and includes integrated support for the 3.3V single supply option.
