85311AMILFT - Renesas Electronics

Description: The 85311I is a low skew, high performance 1-to-2 Differential-to-2.5V/3.3V ECL/LVPECL Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from IDT. The CLK, nCLK pair can accept most standard differential input levels. The 85311I is characterized to operate from either a 2.5V or a 3.3V power supply. Guaranteed output and part-to-part skew characteristics make the 85311I ideal for those clock distribution applications demanding well defined performance and repeatability

85311AMILFT Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (R01AN3801EJ0100) which includes thermal design considerations, such as thermal vias, copper pours, and component placement.
  • Renesas recommends a specific power sequencing scheme in their application note (R01AN3801EJ0100) to ensure proper device operation. This includes powering up the VCC and VDD pins in a specific order and within a certain time frame.
  • While the datasheet specifies an operating temperature range of -40°C to 125°C, Renesas recommends derating the device's performance at temperatures above 85°C to ensure reliability and prevent thermal shutdown.
  • Renesas provides an I2C troubleshooting guide in their application note (R01AN3801EJ0100) which includes tips on signal integrity, clock stretching, and bus arbitration. Additionally, using an I2C analyzer or logic analyzer can help identify issues with the I2C bus.
  • Renesas recommends using 0.1uF to 1uF decoupling capacitors with a voltage rating of 10V or higher, placed as close as possible to the VCC and VDD pins. The exact capacitor value and type may vary depending on the specific application and PCB design.
