Product Details
The AD9152 is a dual, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a maximum sample rate of 2.25 GSPS, permitting a multicarrier generation up to the Nyquist frequency. The DAC outputs are optimized to interface seamlessly with the ADRF6720 analog quadrature modulator (AQM) from Analog Devices, Inc. An optional 3-wire or 4-wire serial port interface (SPI) provides for programming/readback of many internal parameters. The full-scale output current can be programmed over a range of 4 mA to 20 mA. The AD9152 is available in a 56-lead LFCSP. The AD9152 is a member of the TxDAC+® family.
Product Highlights
- Ultrawide signal bandwidth enables emerging wideband and multiband wireless applications.
- Advanced low spurious and distortion design techniques provide high quality synthesis of wideband signals from baseband to high intermediate frequencies.
- JESD204B Subclass 1 support simplifies multichip synchronization in software and hardware design.
- Fewer pins for data interface width with the serializer/deserializer (SERDES) JESD204B four-lane interface.
- Programmable transmit enable function allows easy design balance between power consumption and wake-up time.
- Small package size with an 8 mm × 8 mm footprint.

Design Tools
The JESD204x Frame Mapping Table Generator tool consists of two Windows executables that will allow the user to input any valid combination of JESD204x parameters (L, M, F, S, NP) in order to output a .csv file that illustrates the frame mapping of the JESD204x mode in table format. There is an executable that allows the user to input a single JESD204x mode and another, that allows the user to input the parameters for multiple JESD204x modes in a specified .csv format in order to output a .csv file that illustrates the frame mapping of each of the JESD204x modes that were input into separate tables.
