The HMC-C061 is a double edge triggered D-type FlipFlop (DETDFF) designed to support data transmission rates of up to 50 Gbps. The device operates at half the sampling frequency of the applied data rate. The maximum clock rate is 25 GHz for 50 Gbps input data. The clock input is broadband from DC to 25 GHz. During normal operation, data is transferred to the outputs on both the positive edge and the negative edge of the clock. All input signals to the HMC-C061 are terminated with 50 Ohms to ground on-chip, and may be either AC or DC coupled. The differential outputs of the HMC-C061 may be either AC or DC coupled. Outputs can be connected directly to a 50 Ohm to ground terminated system, while DC blocking capacitors may be used if the terminating system is 50 Ohms to a non-ground DC voltage. The HMC-C061 operates from a single -3.3V DC supply, and is housed in a hermetically sealed module with 1.85mm connectors.
