General Description
The HMC679LC3C is a T Flip-Flop 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-
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. The HMC679LC3C also features an
output level control pin, VR, which allows for loss
compensation or for signal level optimization.
All input signals to the HMC679LC3C are terminated
with 50Ω to ground on-chip, and may be either AC or
DC coupled. Outputs can be connected directly to a
50Ω terminated system, while DC blocking capacitors
may be used if the terminating system is 50Ω to a
non-ground DC voltage. The HMC679LC3C operates
from a single -3.3V DC supply and is available in a
ceramic RoHS compliant 3x3 mm SMT package.
