NF CK1615 / CK1620 Clock Signal Synthesizer

NF CK1615 / CK1620 Clock Signal Synthesizer

Model:CK1615 / CK1620      Country of Origin:Japan

Category:Precision Filter

Overview:

The CK 1620 has a maximum frequency of 500MHz* and the CK 1615 has a maximum frequency of 100MHz; they are high-speed clock signal generators.

Features
Specifications
Application Notes
Functions & Configuration


CK 1620 maximum frequency 500MHz*, CK 1615 maximum frequency 100MHz, are high-speed clock signal generators.
Compared with general-purpose pulse signal generators, not only is there an order-of-magnitude difference in frequency accuracy, but they can also generate any frequency synchronized with an external reference frequency (10MHz).
The high level/low level of the output level can be adjusted independently and set arbitrarily within the range of -2V to +7V, so it can adapt to almost all logic levels.
As clock signal sources of the new era, CK 1620/CK 1615 can meet the needs of a wide variety of applications—their high precision and ease of use are truly remarkable!

 

*There are restrictions on the output level.

 



image.pngHigh-speed clock signal and high resolution
Can output high-speed clock signals from 1kHz up to a maximum of 500MHz*
(CK 1620) or 100MHz (CK 1615). The frequency setting resolution is 1mHz (maximum 12 digits), an extremely high resolution. 
*There are restrictions on the output level.

image.pngHigh accuracy
Adopts a frequency synthesis method to output frequencies with ±5ppm accuracy. In addition, with the "high-accuracy frequency reference option," it can output frequencies with even higher accuracy of ±0.1ppm.

image.pngExternal clock signal input
By inputting a reference frequency (10MHz) from an external source, any frequency synchronized with that frequency can be generated.

image.pngVariable output voltage
The high level/low level of the output voltage can be adjusted independently and set arbitrarily within the range of -2V to +7V, with a high setting resolution of 0.01V.

image.pngLow output jitter
Compared with our company's previous products, output jitter is greatly reduced. (Reference value is 50ps rms)
