Product Description

Product Details
The HMC842LC4B is a 1:2 Fanout Buffer designed to support data transmission rates up to 45 Gbps. The device can also operate with clock signals up to 28 GHz. During normal operation, input data (or clock) is transferred to both output channels. Differential input and output signals of the HMC842LC4B are terminated with 50 Ohms to ground on-chip, and may be either AC or DC coupled. The Outputs can be connected directly to a 50 Ohms-to-ground terminated system, while DC blocking capacitors should be used if the terminating system is 50 Ohms to a non-ground DC voltage.
The HMC842LC4B also features two separate output level control pins, VAC1 and VAC2 which provide loss compensation and signal level optimization for each output channel independently. The HMC842LC4B operates from a single -3.3V DC supply and is available in a ceramic RoHS compliant 4x4 mm SMT package.
