77.76MHz VCXO

_____________________________________________________________________

ELECTRICAL CHARACTERISTICS (continued)

(VDD = 3.135V to 3.465V, TA = -40°C to +85°C or 0°C to +70°C, unless otherwise noted.) (Typical values at +25°C, VDD = 3.3V,

unless otherwise noted.) (Note 1)

Note 1: Limits at -40°C are guaranteed by design and not production tested.

Note 2: Guaranteed by design and not production tested.

Note 3: Tuning linearity typically better than ±10%.
