概要

説明

The IDT1893AF is a lower cost, re-packaged version of the IDT1893Y-10. The IDT1893AF is a fully integrated, Physical Layer device (PHY) that is compliant with both the 10Base-T and 100Base-TX CSMA/CD Ethernet Standard, ISO/IEC 8802-3. The IDT1893AF uses the same proven silicon as the IDT1893Y-10 but offers a lower cost solution by using a lower cost 300 mil. 48-lead SSOP package. The IDT1893AF uses the same twisted-pair transmit and receive circuits as the IDT1893Y-10, and the same recommended board layout techniques apply to the IDT1893AF. The IDT1893AF is intended for Node applications using the standard MII interface to the MAC.
