The DAC568x family of single- and dual-channel digital-to-analog converters from Texas Instruments (Dallas) includes a high-performance 16-bit, dual-channel, 1-Gsample/second device. The single- and dual-channel DAC family features a low-voltage differential signaling (LVDS) data input port at 1 Gbit/s, providing up to a 400-MHz signal bandwidth. The flexible configuration options target basestations, wideband IF transmitters, radar, and test and measurement equipment. Offered in a 9 x 9-mm QFN package, the DAC568x offers a 70 percent space savings over traditional data converters. The devices provide several configuration options to support different transmit architectures such as direct upconversion; real or complex IF; and wireless air interfaces such as W-CDMA, TD-SCDMA, WiMax and LTE. For an output frequency of 160 MHz, the devices achieve 73-dB ACPR for a single-carrier W-CDMA application or 67 dBc for a four-carrier application.
