General Description
The HMC841LC4B is a D-type Flip Flop designed to
support data transmission rates of up to 43 Gbps, and
clock frequencies as high as 43 GHz. During normal
operation, data is transferred to the outputs on the
positive edge of the clock. Reversing the clock inputs
allows for negative-edge triggered applications. The
HMC841LC4B also features an output level control pin,
VAC, which allows for loss compensation or for signal
level optimization.
All input signals to the HMC841LC4B are terminated
with 50 Ohms to ground on-chip, and maybe either
AC or DC coupled. The differential outputs of the
HMC841LC4B may be either AC or DC coupled. Outputs
can be connected directly to a 50 Ohms-to-ground
terminated system, while DC blocking capacitors
should be used if the terminating system is 50 Ohms
to a non-ground DC voltage. The HMC841LC4B
operates from a single -3.3V DC supply and is available
in a ceramic RoHS compliant 4x4 mm SMT package.
