1. General description
2. Features
3. Applications
The DAC1201D125 is a dual-port, high-speed, 2-channel CMOS Digital-to-Analog
Converter (DAC), optimized for high dynamic performance with low power dissipation.
Supporting an update rate of up to 125 Msps, the DAC1201D125 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 DAC1201D125 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 DAC1201D125 is pin compatible with the AD9765, DAC2902 and DAC5662.
