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 selector 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.
