The 13612OR OR/NOR/AND/NAND is designed to support data rates up to 13 Gbps.  Differential inputs and outputs allow the part to be easily configured to perform any of the four logic functions: OR, NOR, AND, and NAND.  THe 13612OR can also be used to convert properly timed NRZ data and clock inputs into RZ / RH data at ultra-high speeds.

All differential data inputs are DC coupled and terminated on chip with 50 Ω resistors to ground.  The differential data outputs are back-terminated on chip with 60 Ω resistors to ground (50 Ω impedance).  For direct-coupled applications, the differential outputs should also be terminated off chip with 50 Ω resistors to ground (GND).  For applications requiring termination to DC levels other than GND, external AC coupling to a good RF ground is required.  See the application note for various terminal examples.

The 13612OR operates from a single –3.3 V power supply and dissipates only 275 mW.  It is available in a 3 mm x 3 mm quad flat no-lead (QFN) package and is also available on an evaluation board with SMA connectors.
