Miniature Crystal Oscillator
DOC-49S SERIES
FEATURES
A very high precision compact crystal oscillator combining a
C-MOS oscillating circuit in crystal resonator (AT-49) case.
DOC-49S1 is a low current consumption and a low harmonic
type DOC-49S2 for high frequencies and DOC-49S3 is a
high power drive capable type.
High reliability is assured by using a completely sealed metal
case with case ground.
