The HMC842LC4B is a 1:2 fan-outbumper, supporting data transfer 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 transmitted to two output channels. The differential input and output signals of the HMC842LC4B are terminated to on-chip ground at 50 Ω and can be AC or DC coupled. The output can be connected directly to a 50 Ω ground termination system, and if a DC voltage is terminated to a non-ground DC voltage through 50 Ω, a DC blocking capacitor should be used.
The HMC842LC4B also integrates two independent output level control pins, VAC1 and VAC2, to provide loss compensation and signal level optimization for each output channel, respectively. The HMC842LC4B operates from a single -3.3V DC supply and is available in a RoHS-compliant 4x4 mm SMT ceramic package.
