3 x 3 QFN Leadless SMT Package General Description
The HMC988LP3E is a an ultra low noise clock
divider capable of dividing by 1/2/4/8/16/32. It is a
versatile device with additional functionality including
adjustable output phase, adjustable delay in 60 steps
of ~ 20 ps, a clock synchronization function, and a
clock invert option.
Housed in a compact 3x3 mm SMT QFN package, the
clock divider offers a high level of functionality. The
device works with 3.3 V supply or may be connected …
