2-16
Most users require a sine wave, a TTL-compatible, a CMOS-compatible, or an ECL-compatible output.  The latter three can be
simply generated from a sine wave.  The four output types are
illustrated below, with the dashed lines representing the supply
voltage inputs, and the bold solid lines, the outputs.  (There is no “standard” input voltage for sine wave oscillators. The input
voltages for CMOS typically range from 1V to 10V.)
