PRODUCT DESCRIPTION

The AD9761 is a complete dual-channel, high speed, 10-bit CMOS DAC. The AD9761 has been developed specifcally for use in wide bandwidth communication applications (e.g., spread spectrum) where digital I and Q information is being processed during transmit operations. It integrates two 10-bit, 40 MSPS DACs, dual 2x interpolation flters, a voltage reference, and digi tal input interface circuitry. The AD9761 supports a 20 MSPS per channel input data rate that is then interpolated by 2x up to 40 MSPS before simultaneously updating each 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 flter that eases the reconstruction flter requirements. The interpolated output of each flter serves as the input of their respective 10-bit DAC.
