HMC854LC5 is a 4:1 multiplexer designed for 28 Gbps data serial applications. The multiplexer latches four differential inputs at the rising edge of the input clock. The device uses the rising and falling edges of a half-rate clock to transmit data serially. A 1/4 rate clock output signal is generated on-chip that can be used to synchronize data with the multiplexer. The multiplexer is DC-coupled and supports broadband operation.
All clock and data inputs of the HMC854LC5 are CML and terminated to a positive supply GND via an on-chip 50 Ω, which can be DC or AC coupled. The differential output source is terminated to 50 Ω and can also be AC or DC coupled. The outputs can be connected directly to a 50-Ω ground termination system or to input driver devices via CML logic. HMC854LC5 also integrates an output level control pin VR for loss compensation or signal level optimization. HMC854LC5 operates from a single -3.3V supply and is available in a ROHS-compliant 5x5 mm SMT package.
