Do you mean delay-generators for 1PPS? Or a finely-tunable frequency synthesizer?
For 1PPS, the fine-delay FMC card might be worth a look: http://www.ohwr.org/projects/fmc-delay-1ns-8cha/wiki afaik it works by first time-stamping the input pulse, then delaying the output with an integer number of clock cycles on the FPGA, and for sub-cycle fine delay it uses programmable hardware delay-lines (these run quite hot on the board), If you need only 1PPS that is synchronous to some input 10MHz signal then the design is much simpler since you don't need to time-stamp an asynchronous input pulse first. SRS DG645 and similar might be worth a look too.
