Description du Produit

Functions : Single 40Gb/s D Gate

The VWA 50002 AA chip is a D Flip Flop for high data rate application typically 10 to 40Gb/s. The chip is designed in 0.18μm SiGe BiCMOS 150GHz process.

The device has two high frequency differential inputs (NRZ_in and Clock) and one differential high frequency output (DFF_Out). The chip is 50Ω single ended and 100Ω differential in and out. The chip can be used single in and out.

The input data stream is transferred to the output for each clock rising edge. The output amplitude is 400mV pp single ended (800mV differential pp).

The different parts of the chip are internally biased using a voltage and currents reference circuit (Bandgap); in order to have the overall RF characteristics of the chip insensitive to the voltage supply the temperature and the process spread. An enable input control pin is used to switch the chip ON or OFF.

Three separate pins are used to bias the chip: one dedicated to the reference circuit the second for the coder core (input buffers and coder core) and the last for the 50Ω output driver. The 3 bias inputs can be separately filtered / decoupled in order to optimize the overall chip performances.
