HMC-C062 Fanout Buffer Module

January 17, 2011

hmc-c062The HMC-C062 is a fanout buffer designed to support data transmission rates of up to 50 Gbps. The device can also operate with clock signals up to 30 GHz. The input is broadband from DC to 30 GHz. During normal operation, input data (or clock) is transferred to both output channels. Differential input signals to the HMC-C062 are terminated with 50 Ohms to ground on-chip, and may be either AC or DC coupled.

The differential outputs of the HMC-C062 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-C062 operates from a single -3.3V DC supply, and is housed in a hermetically sealed module with 1.85mm connectors.
