Need additional information:

Does it have to be pin compatible or is a layout change acceptable?

Are you using all of the features / all of the outputs?  This part outputs up to 6 clocks - do you actually need that many?

Are you one-time programming the configuration (fixed clock rate) or are you writing to it in-system via SPI?

What frequency (or range of freqs) are you trying to generate from what clock source?

There are tons of parts that generate a PLL Clock.

same shopper at the link,  sells that chip, at 11 Euros each
  Perhaps as One off demand, it may not be costly as the item is obsolete
 Bye the way  some Chinese supply houses sell them at around 5$ but they may want volume orders of atleast 10 numbers.
