Note 1: Some specifications are package dependent. Please refer to the spec. sheet of individual packages once a package is
selected..
Note 2: TCXO products ordered without mechanical and electrical frequency tuning should have a frequency tolerance of ±2
ppm (at +25°C) and the frequency stability over temperature will be from that measured value.
