13 Gbps OR/NOR/AND/NAND
- High-speed (up to 13 GHz) digital logic
- High-speed (up to 13 Gbps) serial data transmission systems
- Broadband test and measurement equipment
- NRZ-to-RZ / RH conversion
- Differential encoding for optical DPSK and duobinary transmitter modules
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.
