For those of you that have been waiting for this module the LVDS oscillator module for our low cost Spartan-3 Raggedstone1 development board is now available.

It is capable of generating 31.25MHz to 700MHz and can be programmed serially from the FPGA. We are fitting a 25MHz crystal currently but the module can use a clock provided from the FPGA in the range10-25MHz to generate those more unusual frequencies.
It's not on the shop of our website yet but should appear this coming week or next after that.
