●Product Details
●The AD9135 is a dual, 11-bit, high dynamic range digital-to-analog converter (DAC) that provides a maximum sample rate of 2800 MSPS, permitting a multicarrier generation over a very wide bandwidth. The DAC outputs are optimized to interface seamlessly with the ADRF6720, as well as other analog quadrature modulators (AQMs) 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 typical range of 13.9 mA to 27.0 mA. The AD9135 is available in an 88-lead LFCSP.
●Product Highlights
● 1. Greater than 2 GHz, ultrawide complex signal bandwidth enables emerging wideband and multiband wireless applications.
● 2. Advanced low spurious and distortion design techniques provide high quality synthesis of wideband signals from baseband to high intermediate frequencies.
● 3. JESD204B Subclass 1 support simplifies multichip synchronization in software and hardware design.
● 4. Fewer pins for data interface width with a serializer/deserializer (SERDES) JESD204B eight-lane interface.
● 5. Programmable transmit enable function allows easy design balance between power consumption and wake-up time.
● 6. Small package size with 12 mm × 12 mm footprint.
