CRYSTAL OSCILLATORS Data Sheet 0645A 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
