Functional Diagram

General Description

The HMC859LC3 is a Divide-by-8 w/Reset desig-

ned to support clock frequencies as high as 26

GHz. During normal operation, with the reset pin not

asserted, the output toggles from its prior state on

the positive edge of the clock. Asserting the reset

pin forces the Q output low regardless of the clock

edge state (asynchronous reset assertion). Reversing

the clock inputs allows for negative-edge triggered

applications.

All differential inputs to the HMC859LC3 are CML and

terminated on-chip with 50 Ohms to the positive supply,

GND, and may be DC or AC coupled. Outputs can be

connected directly to a 50 Ohm ground-terminated

system or drive devices with CML logic input. the

HMC859LC3 also features an ouput level control pin,

VR, which allows for loss compensation or signal level

optimization. The HMC859LC3 operates from a single

-3.3 V supply and is available in ROHS-compliant 3x3

mm SMT package.
