Product Descriptions
The AD9763/AD9765/AD9767 are dual-port, high speed,2-channel, 10-/12-/14-bit CMOS DACs. Each part integratestwo high quality TxDAC+®cores,a voltage reference, and digitalinterface circuitry into a small 48-lead LQFP. The AD9763/AD9765/AD9767 offer exceptional ac and dc performancewhile supporting update rates of up to 125 MSPS
The AD9763/AD9765/AD9767 have been optimized forprocessing I and Q data in communications applications . Thedigital interface consists of two double-buffered latches as wellas control logic . Separate write inputs allow data to be written tothe two DAC ports independent of one another. Separate clockscontrol the update rate of the DACs .
A mode control pin allows the AD9763/AD9765/AD9767 tointerface to two separate data ports, or to a single interleavedhigh speed data port. In interleaving mode, the input datastream is demuxed into its original I and Q data and thenlatched. The I and Q data is then converted by the two DACsand updated at half the input data rate .
The GAINCTRL pin allows two modes for setting the full-scalecurrent (IOUTFS) of the two DACs . IOUTFS for each DAC can be setindependently using two external resistors, or IOUTFS for bothDACs can be set by using a single external resistor. See theGain Control Mode section for important date codeinformation on this feature .
