General Description
The HMC953LC4B is a Differential Dual D-Type Flip
Flop with a common clock to support data transmission
rates of up to 14 Gbps, and clock port operation of up
to 14 GHz. During normal operation, dual differential
data is transferred to the respective outputs on the
positive edge of the clock. Reversing the clock inputs
allows for negative-edge triggered applications. The
HMC953LC4B also features an output level control
pin, VR, which allows for loss compensation or for
signal level optimization.
All differential input signals to the HMC953LC4B are
terminated with 50 Ohms to ground on-chip, and
may be either AC or DC coupled. The outputs of the
HMC953LC4B may be operated either differentially
or single-ended. Outputs can be connected directly
to a 50 Ohm terminated system, while DC blocking
capacitors may be used if the terminating system is
50 Ohms to a non-ground DC voltage. The HMC-
953LC4B operates from a single -3.3 V DC supply
and is available in a ceramic RoHS-compliant 4x4 mm
SMT package.
