While searching for a VCO with output frequency as 27MHz, I found the part number SN74S124. But the datasheet doesn't have any formula to determine the exact external capacitance value for 27 MHz. If possible, could you share the formula for the same. I viewed the graph mentioned in the datasheet but if formula is available it would be better.
Also, this is an old product. If possible, could you suggest any new Voltage Controlled Oscillators (VCOs) with output frequency 27 MHz and Voh and Vol within 2V?
Thanks & Regards
