General DescriptionThe 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 Ohms to the positive supply, GND, and may be AC or DC coupled. The differential CML outputs are source terminated to 50 Ohms and may also be AC or DC coupled. Outputs can be connected directly to a 50 Ohm 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 x 4 mm SMT package. |
