CRYSTAL OSCILLATORS
AE-X36DXXX-X Series
PECL/LVPECL UHF VCXO
Description
Data Sheet 0701B
Rev. M
The AE-XXXX Series
of voltage controlled crystal oscillators (VCXO) provides ultra
high frequency with PECL/LVPECL or differential Sine-Wave complementary outputs.
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 17x14
mm SMD package.
