A 48-bit-accumulator DDS chip such as the Analog Devices AD9852 will achieve such frequency resolution: 2^-48= 3.6*10^-15, call it 10^-14. The issue with a DDS is handling the various spurs. Arbitrary function generators such as the Agilent 34220A-001 (the -001 option means that an external 10 MHz reference signal is accepted) will also do the job, in a nice albeit expensive ($2.4K new) package.
