AB-X29NXXX Series
PECL/LVPECL UHF XO
Description
The AB-X29NXXX Series
of crystal oscillators (XO) provides ultra high frequency with
PECL/LVPECL complementary outputs. The outputs can be disabled for test automation or
combining multiple clocks. The device is based on low noise analog harmonic frequency
multiplication, providing exceptionally low Phase Noise and Jitter. It’s packaged in a miniature,
FR-4 based 9x14 mm SMD package
