AB-X32AXXX-X Series
CMOS/LVCMOS HF VCXO
Description
The AB-X32AXXX Series
of voltage controlled crystal oscillators (VCXO) provides high
frequency with CMOS/LVCMOS outputs. The outputs can be Tri-stated for test automation or
combining multiple clocks. The device does not use any frequency multiplication, providing
exceptionally low Phase Noise and Jitter and wide pull. It’s packaged in a miniature, FR-4 based
9x14 mm SMD package
