Functional Diagram
General Description
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 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 4x4 mm
SMT package.
