1. General description

The DAC1001D125 is a dual-port high-speed 2-channel CMOS Digital-to-Analog

Converter (DAC), optimized for high dynamic performance with low power dissipation.

The Supporting an update rate of up to 125 Msps, the DAC1001D125 is suitable for Direct

IF applications.

Separate write inputs allow data to be written to the two DAC ports independently of one

another. Two separate clocks control the update rate of each DAC port.

The DAC1001D125 can interface two separate data ports or one single interleaved

high-speed data port. In Interleaved mode, the input data stream is demultiplexed into its

original I and Q data and latched. The I and Q data is then converted by the two DACs

and updated at half the input data rate.

Each DAC port has a high-impedance differential current output, suitable for both

single-ended and differential analog output configurations.

The DAC1001D125 is pin compatible with the AD9763, DAC2900 and DAC5652.
