8V49NS0312NLGI - Renesas Electronics

Description: The 8V49NS0312 is a flexible Clock Generator with a total of four output dividers: three integer and one that is either integer or fractional. When used with an external crystal, the 8V49NS0312 generates high-performance timing geared towards the communications and datacom markets, especially for applications demanding extremely low phase noise, such as 10, 40 and 100GE. The device is offered in a lead-free 64-VFQFN package and is designed to operate across full industrial temperature range.

8V49NS0312NLGI Frequently Asked Questions (FAQs)

  • A good PCB layout for the 8V49NS0312NLGI involves keeping the power and ground planes separate, using a solid ground plane, and minimizing the distance between the oscillator and the crystal. Additionally, it's recommended to use a low-ESR capacitor for the VCC pin and to decouple the power supply with a 10uF capacitor.
  • To ensure the oscillator starts reliably, make sure the crystal is properly connected, the oscillator capacitors are correctly sized, and the power supply is stable. Also, ensure the oscillator pins are not loaded with external capacitance, and the PCB layout is optimized for oscillator operation.
  • The maximum frequency deviation of the 8V49NS0312NLGI is ±100 ppm over the operating temperature range of -40°C to 85°C.
  • To configure the 8V49NS0312NLGI for low-power operation, use the power-down mode by setting the PD pin high. Additionally, use a low-frequency oscillator, reduce the clock frequency, and minimize the number of active circuits.
  • The recommended operating voltage range for the 8V49NS0312NLGI is 2.97V to 3.63V.
