Functional Diagram
General Description
The HMC959LC3 is a Divide-by-4 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. This results in a divide-by-
four function of the clock input. 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 HMC959LC3 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
HMC959LC3 also features an output level control pin,
VR, which allows for loss compensation or signal level
optimization. The HMC959LC3 operates from a single
-3.3 V supply and is available in ROHS-compliant 3x3
mm SMT package.
