DAC1201D125 Dual 12-bit DAC, up to 125 Msps Rev. 2 — 27 January 2012 Product data sheet 1. General description 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.
