CLOCKS
The CTS CB3 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. Low voltage options are also available.
Tristate control is also standard.
