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.

1] 6I Stability/Temperature combination is not available.
2] These stabilities are not recommended for new designs.
3] Frequency is recorded with only leading significant digits before the ‘M’ and 4 - 6 significant digits after the ‘M’ (including zeros).
[Ex. XMXXXXXX (3M579545), XXMXXXXX (14M31818), XXXMXXXX (125M0000)]
4] CTS Distributors may add a -T or -1 at the end of the part number to indicate Tape and Reel packaging.
Not all performance combinations and frequencies may be available.
Contact your local CTS Representative or CTS Customer Service for availability.
