The AD9763/AD9765/AD9767 have been optimized forprocessing I and Q data in communications applications. Thedigital interface consists of two double-buffered latches as well as control logic. Separate write inputs allow data to be written to the two DAC ports independent of one another. Separate clocks control the update rate of the DACs.
A mode control pin allows the AD9763/AD9765/AD9767 to interface to two separate data ports, or to a single interleavedhigh speed data port. In interleaving mode, the input datastream is demuxed into its original I and Q data and then latched. The I and Q data is then converted by the two DACsand updated at half the input data rate.
The GAINCTRL pin allows two modes for setting the full-scale current (IOUTFS) of the two DACs. IOUTFS for each DAC can be set independently using two external resistors, or IOUTFS for both DACs can be set by using a single external resistor. See theGain Control Mode section for important date codeinformation on this feature.
The DACs utilize a segmented current source architecturecombined with a proprietary switching technique to reduce glitch energy and maximize dynamic accuracy. Each DAC providesdifferential current output, thus supporting single-ended or differential applications. Both DACs of the AD9763, AD9765, or AD9767 can be simultaneously updated and can provide anominal full-scale current of 20 mA. The full-scale currentsbetween each DAC are matched to within 0.1%.
The AD9763/AD9765/AD9767 are manufactured on anadvanced, low cost CMOS process. They operate from a singlesupply of 3.3 V to 5 V and consume 380 mW of power.
Product Highlights
- The AD9763/AD9765/AD9767 are members of a pin-compatible family of dual TxDACs providing 8-, 10-, 12-, and 14-bit resolution.
- Dual 10-/12-/14-Bit, 125 MSPS DACs. A pair of high performance DACs for each part is optimized for low distortion performance and provides flexible transmission of I and Q information.
- Matching. Gain matching is typically 0.1% of full scale, and offset error is better than 0.02%.
- Low Power. Complete CMOS dual DAC function operates on 380 mW from a 3.3 V to 5 V single supply. The DAC full-scalecurrent can be reduced for lower power operation, and a sleepmode is provided for low power idle periods.
- On-Chip Voltage Reference. The AD9763/AD9765/AD9767each include a 1.20 V temperature-compensated band gapvoltage reference.
- Dual 10-/12-/14-Bit Inputs. The AD9763/AD9765/AD9767each feature a flexible dual-port interface, allowing dual orinterleaved input data.
Applications
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
