up to 8 addressable dividers per sPi bus

3.3 V operation or 5 V operation with optional on-

chip regulator for best performance

3 x 3 QFn leadless sMt Package

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

to 5 V supply and utilize the optional on-chip regulator.

this on-chip regulator may be bypassed.

up to 8 addressable HMC988lP3E devices can be

used together on the sPi bus.

the HMC988lP3E is ideally suited for data converter

applications

with

extremely
