7101 series Fund. Crystal oscillator module IC with fundamental oscillation frequency range of 16MHz to 100MHz. The oscillator circuit stage has a voltage regulator drive, which reduces current consumption and frequency deviation due to fluctuations in the supply voltage. Even with those enhanced functions built in, its small chip size enables it to be implemented in a 1612 package.
