Crystal controlled ramp generator

This project grew out of the need to generate a linear crystal controlled ramp signal for the HP 8620C RF Sweep Oscillator. It was inspired by a previously released ramp generator design. There are two problems with this design: it uses a non-standard 16.384MHz crystal oscillator; its ramp has zero fall/return/blank times.
