Description
The AD9857ASTZ is a high-performance, high-speed, and 14-bit digital-to-analog converter
(DAC) integrated with clock multiplier circuitry, digital filters, direct digital synthesizer
(DDS), and other digital signal processing (DSP) functions. This integration results in a
complete quadrature digital upconverter device. It is designed to be a universal I/Q modulator,
agile upconverter, interpolating DAC, or single-tone DDS for communication applications, where
cost, size, power dissipation, and dynamic performance are crucial.
Specifications and features
- 200 MHz internal clock rate
- 14-bit data path
- 80 dB SFDR @ 65 MHz (±100 kHz) AOUT
- 4× to 20× programmable reference clock multiplier
- Reference clock multiplier PLL lock detect indicator
- Internal 32-bit quadrature DDS
- 8-bit output amplitude control
- Four programmable, pin-selectable signal profiles
- SIN(x)/x correction (inverse SINC function)
- 10 MHz serial, 2-wire or 3-wire SPI®-compatible
- 3.3 V single supply
- Single-ended or differential input reference clock
- 80-lead LQFP surface-mount packaging
- Three modes of operation:
- Quadrature modulator mode
- Single-tone mode
- Interpolating DAC mode
Application Scenarios
- HFC data, telephony, and video modems
- Wireless base station
- Agile, LO frequency synthesis
- Broadband communications
Comparison
Advantages- Integrates a high-speed DDS and a high-performance DAC on a single chip, reducing the cost and size of the device
- Excellent dynamic performance and high resolution owing to its 14-bit digital-to-analog conversion and internal clock rate of 200MHz
- Single-ended or differential input voltage reference clock
- Easy to use with simplified control interface 10 MHz serial, 2-wire or 3-wire SPI®-compatible
- Three modes of operation for different applications
- Provides SIN(x)/x correction (inverse SINC function) to enhance performance
Disadvantages- High-power dissipation as it consumes more power
- Limited signal profiles
- Voltage reference clock is required
- May not support some specific applications
