The HMC954LC4B is a 2 to 1 Multiplexer designed for 32 Gbps data serialization. The mux latches the two differential inputs on a rising edge of the input clock. The device uses both rising and falling edges of the half-rate clock to serialize the data. The HMC954LC4B also features an output level control pin, VR, which allows for loss compensation or for signal-level optimization.
All differential inputs to the HMC954LC4B are CML and terminated on-chip with 50 Ω to the positive supply, GND, and may be AC or DC coupled. The differential CML outputs are source terminated to 50 Ω and may also be AC or DC coupled. Outputs can be connected directly to a 50 Ω ground-terminated system or drive devices with CML logic input. The HMC954LC4B operates from a single −3.3 V supply and is available in a ceramic ROHS-compliant 4 × 4 mm SMT package.
