RF Signal Source AD9959 Signal Generator 4 Channel DDS Module



Specifications:
- Size: 81*61mm
- Power voltage: DC5V

Chip:
- 4* 500 MSPS synchro DDS channel
- Independent frequency/phase/range for all the channel
- Delay for thechange of frequency/phase/range
- Great isolation for channels
- Frequency sweeping fucntion
- 16 order modulation
- Programmable DAC full range current

Chip application:
- (LO) frequency synthesis

- RF source for AOTF

Description:
- AD9959 can be used for filtering,amplification and other analog procassing or imbalance among the signals
- AD9959 can exacuate 16 orders frequency,phase or range (FSK,PSK,ASK).Can be Executive modulation.Also it supports linear frequency,range or phase scanning, for radar or instruments.
- The seriel I/O port can support multi configuration. It provides SPI compatible working mode. 4 data pins (SDIO_O/SDIO_1/SDIO_2/SDIO_3)
- DDS technology. Integrated 10bit DAC, 32 bit for each channel, 14bit phase shift and 10 bit output proportional multiplier.
- DAC output takes power voltage as reductometry source
- When taking REFCLK as input and DAC output, this DDS can be used as high resolution frequency divider. All channel share REFCLK input source which can be drived directly. Or used with built in REFCLK that up to 500 MSPS. Multiplication factor of PLL, programmable range is 4-20. There is also oscillating circuit for REFCLK input. Can take the external crystal oscillator as REFCLK source. The frequency of crystal oscillator must be 20MHz-30MHz.
- AD9959 adopts 56pin LFSP encapsulation. DDS inner core (AVDD/DVDD pin), 1.8V power supply. Digital I/O interface (SPI) working under 3.3V and needs to connect the DVDD_I/O (Pin 49) to the 3.3V voltage.
- Working temperature is -40~85 degree C.
