MT88L70AS1 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the signal traces short and away from noise sources. Use a 50-ohm transmission line for the clock input.
  • Use a low-ESR capacitor (e.g., 0.1uF) between VCC and GND, and a 10uF capacitor between VCC and GND for bulk decoupling. Ensure the power supply is stable and has low ripple.
  • The maximum clock frequency is 1.5 GHz, but it's recommended to operate at 1.2 GHz or lower for optimal performance and to minimize power consumption.
  • For differential clock input, connect the clock signal to CLK+ and CLK-, and tie the CLK- pin to GND through a 50-ohm resistor. For single-ended clock input, connect the clock signal to CLK+ and tie CLK- to GND.
  • Use a 50-ohm series resistor and a 50-ohm parallel resistor to GND for each output pin to ensure proper termination and minimize reflections.
