The DM7080 is a high-speed D-type flip flop fabricated using 1-μm HBT GaAs technology. Its high output voltage, excellent rise and fall time and the high eye diagram quality at all clock frequencies makes the DM7080 suitable for very high speed and complex digital applications such as decision circuits, waveform shaping, register implementation, and timing adjustment. The device consists of a master-slave latch designed using an ECL topology guarantee high-speed operation. The data and clock inputs and data outputs are DC coupled. At the data input port, the DM7080 tolerates a wide range of operating conditions, and the internal 50-ohm resistors avoid the need for external terminations for impedance matching. The DM7080 uses SCFL I/O levels and allows either single-ended or differential data input and output. An on-chip output buffer provides an excellent eye diagram at a 12.5 GHz clock frequency.
