CBM97D79TQ Dual , 16 bit, 1 GSPS analog-to-digital converter

The CBM97D79TQ is dual, 16-bit, high dynamic range, digital-to-analog converters (DACs)that provide a sample rate of 1 GSPS, permitting multicarrier generation up to the Nyquist frequency. They include features optimized for direct conversion transmit applications, including complex digital modulation, and gain and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators such as the ADL537XFMOD Series modulator made by ADI company. The three-wire interface provides for programming and readback of many internal parameters. Full-scale output current can be programmed over a range of 10 mA to 30 mA. The devices are manufactured on an advanced 0.18μm CMOS process and operate on 1.8 V and 3.3 V supplies for a total power consumption of 1.0W. The CBM97D79TQ can be functionally divided into digital filter unit, DAC core unit, clock (including internal PLL) unit, auxiliary DAC, multi-chip synchronization unit, etc. The digital part performs digital interpolation, digital domain real modulation and complex modulation on the input signal. The DAC core converts the digital signal from digital to analog. SPI configures all of the chip. The clock unit provides high-quality clock for the circuit, four auxiliary DACs are usedfor channel gain and offset correction, The multi-chip synchronization unit is responsible for the synchronization function between multiple chips.
