CMOS/LVCMOS HF VCTCXO
AB-XC3XXX-X Series
Description
The AB-XC3XXX Series
of voltage controlled, temperature compensated crystal
oscillators (VCTCXO) provides high frequency with CMOS/LVCMOS output. The
outputs can be tristated for test automation or combining multiple clocks. The device
does not use any frequency multiplication, providing exceptionally low Phase Noise and
Jitter. It’s packaged in a miniature, FR-4 based 9x14 mm SMD package
