85408BGLF - Renesas Electronics

Description: The 85408 is a low skew, high performance 1-to-8 Differential-to-LVDS Clock Distribution Chip from IDT. The 85408 CLK, nCLK pair can accept most differential input levels and translates them to 3.3V LVDS output levels. Utilizing Low Voltage Differential Signaling (LVDS), the 85408 provides a low power, low noise, low skew, point-to-point solution for distributing LVDS clock signals. Guaranteed output and part-to-part skew specifications make the 85408 ideal for those applications demanding well defined perf

85408BGLF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1mm clearance around the package for airflow and heat dissipation.
  • Use an external reset circuit with a capacitor and resistor to ensure a clean POR and BOR. The recommended values are 10uF and 10kΩ, respectively.
  • Use an external crystal oscillator with a frequency of 12MHz to 24MHz. Ensure the clock signal is routed close to the MCU and away from noisy signals.
  • Use the MCU's built-in power-saving modes, such as idle and sleep modes. Optimize your code to minimize CPU usage and use peripherals with low power consumption.
  • Use a metal shield or a Faraday cage to enclose the MCU and surrounding components. Ensure proper grounding and decoupling of power supplies to minimize electromagnetic interference.
