Resources for 8V49NS0312
Description
The 8V49NS0312 is a flexible cock 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 the full industrial temperature range.
The 8V49NS0312 provides versatile frequency configurations and output formats and is optimized to deliver excellent phase noise performance. It delivers an optimum combination of high clock frequency and low phase noise performance, combined with high-power supply noise rejection. Flexibility and ease of programmability allow these devices to be used in a variety of clock trees while reducing engineering effort. The device is programmable through an I²C interface and also supports I²C master capability to allow the register configuration to be read from an external EEPROM. Renesas’ Timing Commander™ software tool enables a fast and easy reconfiguration of the devices.
