8V41NS0412 Datasheet | Renesas

Description The 8V41NS0412 is a clock generator with four output dividers: three integer, and one that is either integer or fractional. When used with an external crystal, the 8V41NS0412 generates high performance timing geared towards the munications and data markets, especially for applications demanding extremely low phase noise, such as 10GE, 40GE, 100G, and 400GE. The 8V41NS0412’s versatile frequency configurations are optimized to deliver excellent phase noise performance. The device delivers an optimum bination of high clock frequency and low-phase noise performance, bined with high-power supply noise rejection. The 8V41NS0412 supports HCSL type of output level on eleven of its outputs. In addition, there is a single LVCMOS output that has the option of providing a generated clock or acting as a reference bypass output. The device can be configured to deliver specific configurations under pin control only, or additional configurations through an I2C serial interface by an external processor. The 8V41NS0412 is offered in a lead-free (Ro HS6) 64-VFQFN package.
