Integrated Device Technology's highly flexible 12-output clock generator features ultra-low jitter performance to meet the demanding requirements of the communications and datacom markets. The IDT 8V49NS0312 enables the high-performance timing needed for complex system environments such as those seen in 10, 40 and 100 Gigabit Ethernet systems, according to the company.

The 8V49NS0312 features three integer dividers and a fourth divider that can function in either integer or fractional mode and provide one LVCMOS and 11 differential outputs. Integration with IDT’s Timing Commander software tool enables fast and easy reconfiguration of the device, which aids engineers when dealing with overall design iterations and time to market.

The device provides multiple output frequencies with little to no frequency mixing—which is often an issue in similar devices in the market. Integrated PSNR circuitry provides superior power supply rejection, simplifying external filter requirements. The device’s flexibility in delivering specific output configurations—through pin control or additional configurations through an I2C interface—allows it to be used in a variety of clock trees while reducing overall engineering design effort.

“Today’s designers require timing devices with ultra-low phase jitter to meet the requirements for advanced communications systems,” said Kris Rausch, general manager of IDT’s Timing Products Division. “The 8V49NS0312 accomplishes this while delivering an optimal combination of mixed-clock frequencies and low phase noise performance, combined with high power supply noise rejection. The result is robust performance across a wide range of frequencies.”

The 8V49NS0312 is offered in a 64-VFQFN package and is designed to operate across the full industrial temperature range.

The 8V49NS0312 is available now for Rs. 439.19 ($6.50) each in lots of 10,000.
