Frequency translator ICs from IDT translate 8kHz-710MHz to 1MHz -1.3GHz range

Integrated Device Technology, Inc has announced the Universal Frequency Translators (UFTs) 840N202I, 849N202I and 849N212I to accept input frequencies from 8kHz to 710MHz and translate them into output frequencies from 1MHz - 1.3GHz, without the limitation of an integer relationship between input and output for applications such as in communications and networking equipment that carry multi-service traffic. These devices features the capability to adjust the degree of jitter attenuation performed, allowing the same device to be used in multiple applications or scenarios without the need to change components on the circuit board.

"Our newest UFT family offers both flexibility and performance at an attractive price point," said Fred Zust, vice president and general manager of the Communications Division at IDT. "The ability to choose an output frequency that isn't a multiple of the input simplifies our customers' designs, reducing cost and improving time-to-market. With RMS jitter of less than 0.5 picoseconds (ps) for many translation scenarios, and some less than 0.3ps, these devices can be used in high performance applications requiring very precise clocks. IDT is the leader in silicon timing solutions and this new family of devices reinforces that leadership position."

IDT explains that with a simple and intuitive graphical user interface (GUI) programming tool, users can quickly configure output frequencies and mode of operation and generate the configurations that can then be permanently stored in the device and UFT family supports two redundant inputs that can be switched automatically in the event of a failure on the primary input, also able to control the rate of phase change on the output as the device switches between the inputs to optimize the handoff.

Pricing and Availability: The IDT 840N202I, 849N202I, 849N212I UFT devices are currently sampling to qualified customers and are available in a 6x6mm 40-ld QFN package.
