ORDERING INFORMATION

CB1V8

FREQUENCY STABILITY

6 = ± 20 ppm

(-20°C to +70°C only)

5 = ± 25 ppm

3 = ± 50 ppm (standard)

2 = ± 100 ppm

(-40°C to +85°C only)

OPERATING TEMPERATURE RANGE

C = -20°C to +70°C (standard)

I = -40°C to +85°C

FREQUENCY IN MHz

M - indicates MHz and decimal point.

Frequency is recorded with minimum 4

significant digits to the right of the "M".

Example Part Number: CB1V83C032M7680

DESCRIPTION

The CB1V8 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.
