ORDERING INFORMATION
SUPPLY VOLTAGE FREQUENCY IN MHz LV = +3.3Vdc Blank = +5.0Vdc M - indicates MHz and decimal point. Frequency is recorded with minimum 4 significant digits to the right of the "M". FREQUENCY STABILITY OPERATING TEMPERATURE RANGE C = -20°C to +70°C (standard) I = -40°C to +85°C 6 = ± 20 ppm 5 = ± 25 ppm 7 = ± 32 ppm 3 = ± 50 ppm (standard) 2 = ± 100 ppm (-40°C to +85°C only) Example Part Number: CB3LV-3C-32M7680 or CB3-3I-32M7680
DESCRIPTION
The CB3/CB3LV is a ceramic packaged Clock oscillator offering reduced size and enhanced stability. The small size means it is perfect for any application. The enhanced stability means it is the perfect choice for today’s communications applications that require tight frequency control.
