Dear Friends,

I have designed a PLL using ADF4110 from Analog Devices.
The Output of the PLL is 180MHz Sine wave. This i need to fed to DDS Synthesizer AD9851 4m Analog Devices.As per the datasheet of AD9851 the reference signal is CMOS/TTL-level pulse train.So i want to convert this 180MHz Sine to TTL(3.5V min)
Can some body suggest some IC which can operate in the frequency range i have specified above.
It's Very Urgent.Please help me..

Thanks and Regards,
Y.Viswanath.
 

you can use maxim 220 IC for conversion to logic level just check out the datasheet of that..
 

Hi,
Thanks for the response.
Max220 is RS232 driver right.How can i use this in my application?

Regards,
Y.Viswanath
