AD5160 as resistance to eliminate clock reflection

Thread Summary

The user inquired about using the AD5160 to replace a resistor in an oscillator circuit to manage clock signal reflection and overshoot while sweeping from 1kHz to 100MHz. The support engineer confirmed that the AD5160's bandwidth is limited to 1.2MHz, making it unsuitable. The AD5258, with a -3dB bandwidth of 18MHz, was also considered but is not applicable for the 100MHz requirement.

Hello,

I have a question about typical oscillator circuit and AD5160.

In typical oscillator circuit, if we want to avoid clock signal reflection or overshoot when clock at rising edge, there is recommend to add a resistance to reduce them,

however, in my application I often need to sweep clock range about 1k to 100MHz as a data converter's sample clock, so I need to replace this resistance frequently..

My question is whether the AD5160 can replace the SMD resistance in fig.1 ?

                                ( fig.1: OSC circuit )

Thank you!
