The HMC954LC4B is a 2:1Multiplexer, designed for 32 Gbps data serial applications. The multiplexer latches two differential inputs on the rising edge of the input clock. The device uses the rising and falling edges of a half-rate clock to transmit data serially. The HMC954LC4B also integrates an output level control pin, VR, which can be used for loss compensation or signal level optimization.
All differential inputs of the HMC954LC4B are CML and terminated to the positive supply GND via an on-chip 50 Ω, either AC or DC coupled. The differential CML output is terminated to 50 Ω and can also be AC or DC coupled. The outputs can be connected directly to a 50-Ω ground-terminated system or via CML logic input drivers. The HMC954LC4B operates from a single -3.3 V supply and is available in a RoHS-compliant 4x4 mm SMT ceramic package.
