HMC955 1:2 Demux w/High Speed Invert & Programmable Output Voltage

The HMC955LC4B is a 1 to 2 Demux designed to support data transmission rates up to 32 Gbps. The demux uses both rising and falling edges of the half-rate clock to sample the data in sequence 01-02 and latches the data on the rising edge into the differential outputs. The demux also has high-speed clock synchronous invert input that allows for scrambling of the data. The HMC955LC4B also features an output level control pin, VR, which allows for loss compensation or for signallevel optimization.

All differential inputs to the HMC955LC4B 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 HMC955LC4B operates from a single -3.3 V supply and is available in a ceramic ROHS-compliant 4 x 4 mm SMT package.
