Can I use the chip of HMC492LP3 to get a 5G sine wave while giving a input of 10G sine wave ?

Can I use the chip of HMC492LP3 to get a 5G sine wave while giving a input of 10G sine wave ? For the datasheet gives an example of the 100M square wave,but I want to get an standard output sine wave,so dose this chip have such function? and what about  other chips that can meet the function?

    Hi,

    The HMC492 frequency divider output will be a square wave with strong odd harmonics.  If you wish, you can low pass or band pass filter the output to achieve a sine wave.

    Generally speaking, most frequency dividers/counters are edge triggered logic devices and the output will be square in nature (regardless if the input is sine, square, pulse, etc).  The fixed even-divisors products will have a duty cycle 50% (odd harmonics).  Whereas, the fixed odd-divisors and counter products will have a duty cycle proportional to 1/N, which means both even and odd harmonics may be present depending upon product and configuration.
