Need to design an oscillator 500K~10MHz range. -5V to 5V amp.. rise time and fall time should be lesser than 5ns.
freq resolution is not an issue. rise and fall time and -5to +5 voltage are important criteria.
Initial idea was to generate the frequency using a PLL or VCO chip (get 0-5V swing) then use high precision op-amp to get the negative swing.
Rise and fall times are way over 5ns when using the high-precision op-amp to generate the negative swing.
Any one used SN74LV4046AN PLL-with-VCO IC from TI?? https://focus.ti.com/docs/prod/folders/print/sn74lv4046a.html
Any pointer on this chip or on the overall approach will be really helpful
