ISL35411DRZ-TS - Renesas Electronics

Description: The ISL35411 is a quad de-emphasis driver with extended functionality for advanced protocols operating with line rates up to 11.1Gbps. It integrates a high-speed driver/limiting amplifier with built-in de-emphasis to compensate for the frequency-dependent attenuation of PCB traces and twin-axial copper cables. Supported protocols include 4k/8k video capable DisplayPort v1.3 (HBR1/2/3), InfiniBand (QDR), 40G Ethernet (40GBASECR4/SR4) and 10G SFP+ specification (SFF-8431). Used in conjunction with Renesas' IS

ISL35411DRZ-TS Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note AN1995, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The ISL35411DRZ-TS has a thermal pad that must be connected to a thermal plane on the PCB to dissipate heat. A thermal via array or a copper pour on the PCB can be used to dissipate heat. Additionally, a thermal interface material (TIM) can be used to improve heat transfer between the device and the heat sink.
  • The recommended input capacitor value is 10uF to 22uF, and a low-ESR ceramic capacitor (X5R or X7R dielectric) is recommended. The input capacitor should be placed as close as possible to the VIN pin to minimize noise and ensure stable operation.
  • The output voltage of the ISL35411DRZ-TS can be configured using an external resistor divider network connected to the FB pin. The resistor values can be calculated using the formula provided in the datasheet, and the output voltage can be adjusted from 0.8V to 5.5V.
  • The maximum input voltage that can be applied to the ISL35411DRZ-TS is 6.5V. Exceeding this voltage may damage the device. It is recommended to use a voltage regulator or a voltage limiter to ensure that the input voltage does not exceed the maximum rating.
