AB-A3DCXXX-X Series
LVDS HF VCXO
Description
The AB-A3DCXXX Series
of voltage controlled crystal oscillators (VCXO) provides high
frequency with LVDS complementary outputs. The outputs can be disabled 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
