CRYSTAL CLOCK OSCILLATORS
Data Sheet 0629G
LVPECL UHF VCXO
SD-X36BXXX-X Series
Description
Rev. J
The SD-X36BXXX Series
of voltage controlled crystal oscillators (VCXO) provides ultra high
frequency with LVPECL complementary output. The outputs can be Tri-stated for test automation or
combining multiple clocks. The device is based on low noise analog harmonic multiplication for
higher frequencies, and packaged in a miniature, low profile leadless ceramic SMD package with 6
gold plated pads.
