描述
The DAC1617D1G0HN is a high-speed 16-bit dual-channel digital-to-analog converter (DAC) with selectable x2, x4, and x8 interpolating filters optimized for multi-carrier and broadband wireless transmitters at sample rates of up to 1Gsps. Supplied from a 3.3V and a 1.8V source, the DAC1617D1G0HN integrates a differential scalable output current of up to 34mA. The DAC1617D1G0HN is capable of meeting multi-carrier GSM specifications. The serial peripheral interface (SPI) provides full control of the DAC1617D1G0HN. The DAC1617D1G0HN integrates a low voltage differential signaling (LVDS) double data rate (DDR) receiver interface, with an on-chip 100Ω termination.
