DAC satisfies requirements for multistandard systems

The dual-channel 1.2-Gsample/s 16-bit AD9122 D/A converter supports the high data rates and complex modulation schemes required for advanced multicarrier wireless and broadband communications equipment throughout the world. Housed in a 72-pin LFCSP, which is 50% smaller than previous-generation DACs, the part features 400-MHz bandwidth and an on-chip 32-bit NCO that allows flexible placement of the IF.

The wireless communications standards that the DAC supports include GSM, WCDMA, TD-SCDMA, CDMA2000, WiMAX, and LTE. Operating with the on-chip PLL at a DAC output frequency of 150 MHz, the AD9122 delivers a 76-dB ACLR for single-carrier WCDMA applications.

For the most demanding wireless communications applications, the part can achieve 83-dBc ACLR using an external PLL. The AD9122 includes integrated interpolation filters with selectable interpolation factors of 2, 4, and 8. ($34.95 ea/1,000 — available now.)
