TQ6111D

The TQ6111D is designed as one kind of GaAs instrumentation or video DAC module,it is produced by thr TriQuint.The GIGADAC converter series extends the operation of high-speed D/A converters to the 600-1000 Ms/s range.Based upon the TriQuint GaAs IC Q-LOGIC component series.The GIGADAC is a available in two versions(600 Ms/s or 1000 Ms/s).Multiplexed data inputs allow the data circuitry to run half as fast as the DAC.On-chip output terminations give clean transitions.The TQ6111D and TQ6112D DACs are designed for high-speed instrumentation system applications such as sub-nanosecond risetime arbitrary waveform generation and also for video applications(a blanking input overrides all data inputs).

Here are the features of the TQ6111D:(1)1 Gs/s minimum conversion rate and 600 Ms/s minimum conversion rate;(2)nultiplexed 2:1 data inputs;(3)setting time:1 ns,to within 1%;2 ns,to within 0.5%;(4)ECL compatible input levels;(5)8-bit resolution;(6)glitch energy:<25 pV-sec.

The last point is the product specifications of TQ6111D:(1)conversion speed:600 Ms/s minimum(TQ6111B) and 1 Gs/s minimum(TQ6112B);(2)setting time:setting time:1 ns,to within 1%;2 ns,to within 0.5%;(3)available accuracies:8 bits;(4)power dissipation:5 watts(typical);(5)output impedance:50 Ohms/0.3 pF;(6)output compliance range:+2,-1.5 volts.
