DAC for wireless applications

DAC for wireless applications

Texas Instruments has introduced a 16-bit, dual channel, 800 MSps DAC designed for wireless base stations, software-defined radio applications and multi-frequency test equipment. Offered in a space-saving 64-pin 9 x 9 mm QFN package, the DAC5688 features enhanced performance to support existing 3G applications, including WCDMA and TD-SCDMA, and emerging 4G applications, including WiMAX and LTE. For instance, for an output frequency of 70 MHz, the device achieves 81 dBC ACLR for a single-carrier WCDMA application. The dual CMOS data bus provides 250 Mbps input data transfer per DAC channel. Several input data options are available including dual-bus data, single-bus interleaved data, even and odd multiplexing at half-rate, and an input FIFO with either external or internal clock, which eases interface timing. Input data can be interpolated two, four or eight times by on-board digital interpolating FIR filters with greater than 80 dB stop-band attenuation.
