AD9257 Expected VIN Load

I am wondering what the recommended load (50Ω, 100Ω, 1kΩ, etc.) is for the VIN+/- input pins of the AD9257. We will be potentially using the ADA4930 as a single-ended to differential driver before the ADC, and I'm not sure what load to put on the outputs of the driver.


Examples from the AD9257 datasheet on page 21 show an expected 100Ω load for the CLK+/- input pins, but I cannot find similar examples for VIN+/- pins.


Thanks for your assistance.
