1893AFLF - Renesas Electronics

Description: 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

1893AFLF Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APL-000001) which includes thermal vias, thermal pads, and heat sink recommendations to ensure optimal thermal performance.
  • Renesas recommends using an external overcurrent protection circuit, such as a fuse or a dedicated overcurrent protection IC, to prevent damage to the device. The datasheet provides guidelines for selecting the appropriate overcurrent protection component.
  • Renesas recommends a power-up sequence of VCC, then VDD, and finally EN (enable) to ensure proper device operation and prevent latch-up. The datasheet provides a detailed power-up sequence diagram.
  • Renesas provides an I2C troubleshooting guide in their application note (APL-000002) which includes tips for debugging I2C communication issues, such as checking clock frequency, data line integrity, and slave address configuration.
  • The 1893AFLF has an operating temperature range of -40°C to 125°C, but Renesas recommends derating the device's performance at temperatures above 85°C to ensure reliable operation.
