The AD9761ARSZ is a complete 2-channel high speed 10-bit CMOS Digital-to-analog Converter (DAC) has been developed specifically for use in wide bandwidth communication applications where digital I and Q information is being processed during transmit operations. The AD9761 supports a 20MSPS per channel input data rate that is then interpolated by 2x up to 40MSPS before simultaneously updating DAC. The interleaved I and Q input data stream is presented to the digital interface circuitry, which consists of I and Q latches as well as some additional control logic. The data is de-interleaved back into its original I and Q data. An on-chip state machine ensures the proper pairing of I and Q data. The data output from each latch is then processed by a 2x digital interpolation filter that eases the reconstruction filter requirements. The interpolated output of each filter serves as the input of its respective 10-bit DAC.
