General Description
The HMC-C061 is a double edge triggered D-type Flip-
Flop (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.
