8V49NS0412 Datasheet NG Clock Generator

Manufacturer: IDT

General Description

The 8V49NS0412 is a clock generator with four output dividers: three integers, and one that is either integer or fractional.

When used with an external crystal, the 8V49NS0412 generates high-performance timing for the communications and datacom markets, especially for applications that demand extremely low phase noise, such as 10GE, 40GE, 100G, and 400GE.

The 8V49NS0412 provides versatile frequency configurations and output formats, and is optimized to deliver excellent phase noise performance.

Overview
