Functional Diagram
General Description
The HMC729LC3C is a T-Type Flip-Flop w/Reset
designed 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-
two 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 HMC729LC3C are CML
and terminated on-chip with 50 Ohms to the positive
supply, GND, and may be DC or AC coupled. The
differential CMl outputs are source terminated to to 50
Ohms and may also be AC or DC coupled. Outputs can
be connected directly to a 50 Ohm ground-terminated
system or drive devices with CML logic input. The
HMC729LC3C operates from a single -3.3 V supply and
is available in ROHS-compliant 3x3 mm SMT package.
