Description
The 2.5V S1634 is a crystal-controlleꢁ,
low-current, low voltage oscillator ꢀro-
viꢁing ꢀrecise rise anꢁ fall times to ꢁrive
high ꢀerformance aꢀꢀlications. The min-
iature, low ꢀrofile leaꢁless ceramic ꢀack-
age has golꢁ-ꢀlateꢁ contact ꢀaꢁs, iꢁeal
for toꢁay's ꢀick-anꢁ-ꢀlace SMT environ-
ments. These oscillators are containeꢁ in
a ruggeꢁ, suꢃcomꢀact 3.2x5mm ꢀackage
iꢁeal for high ꢁensity aꢀꢀlications re-
quiring tight frequency staꢃility over a
range of oꢀerating conꢁitions.
