AA-X36KXXX-X Series
PECL VCXO
Description
The AA-X36KXXX Series
of crystal oscillators (XO) provides low phase noise PECL/LVPECL
complementary outputs. The outputs can be disabled for test automation or combining multiple
clocks. The device packaged in a miniature, low profile, leadless FR-4 based package with gold
plated pads, which enhances compatibility with PCB material.
