I can't think of a use case I wouldn't use something else other than this IC for. The BOM cost is really high as well.

A Si5351 (£1), crystal (£0.40) and microcontroller (£0.50) to drive it are cheaper and more flexible. 0-200MHz, three independent outputs, rock solid frequency stability.

For everything inbetween a couple of CMOS gates are probably good enough with an RC circuit.
