AA-X53AXXX Series
LVCMOS XO
Description
The AA-X53AXXX Series
of crystal oscillators (XO) provides customer selectable four
frequency LVCMOS output in wide frequency range up to 250 MHz. The output 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.
