DAC1617D1G0

DAC1617D1G0 Dual 16-bit DAC, LVDS interface, up to 1 Gsps, x2, x4 and x8 interpolating Rev. 4 — 12 December 2012 Product data sheet 1. General description The DAC1617D1G0 is a high-speed 16-bit dual channel Digital-to-Analog Converter (DAC) with selectable ×2, ×4 and ×8 interpolation filters. The device is optimized for multi-carrier and broadband wireless transmitters at sample rates of up to 1 Gsps. Supplied from a 3.3 V and a 1.8 V source, the DAC1617D1G0 integrates a differential scalable output current up to 34 mA. The Serial Peripheral Interface (SPI) provides full control of the DAC1617D1G0. The DAC1617D1G0 integrates a Low Voltage Differential Signaling (LVDS) Double Data Rate (DDR) receiver interface, with an on-chip 100 Ω termination. The LVDS DDR interface accepts a multiplex input data stream such as interleaved or folded. An internal LVDS input auto-calibration ensures the robustness and stability of the interface. Digital on-chip modulation converts the complex I and Q inputs from baseband to IF. A 40-bit Numerically Controlled Oscillator (NCO) sets the mixer frequency. High resolution internal gain, phase and offset control provide outstanding image and Local Oscillator (LO) signal rejection at the system analog modulator output. An inverse (sin x) / x function ensures a controlled flatness 0.5 dB for high bandwidths at the DAC output. Multiple device synchronization allows synchronization of the outputs of multiple DAC devices. MDS guarantees a maximum ske...
