I have a W & G freq generator 200 hz - 20 khz and want to use it for 136 khz as a driving tx source. Is there a chip device that multiplies this up to the desired freq. say x 8 1600 hz - 160 khz. I am trying to avoid the convential method with descrete components, another approach would be to mix/hetrodyne it to the desired freq with an appropriate xtal osc cct. All advice appreciated. 73 de Mal/G3KEV
