The output frequency\nand phase are software programmable, allowing easy tuning. No external\ncomponents are needed. The frequency regis ters are 28 bits; with a 25 MHz\nclock rate, resolution of 0.1 Hz can be achieved. Similarly, with a 1 MHz\nclock rate, the AD9833 can be tuned to 0.004 Hz resolution.The AD9833 is\nwritten to via a 3-wire serial interface. This serial interface operates at\nclock rates up to 40 MHz and is compatible with DSP and microcontroller\nstandards. The device operates with a power supply from 2.3 V to 5.5 V.The\nAD9833 has a power-down function (SLEEP). This allows sections of the device\nthat are not being used to be powered down, thus minimizing the current\nconsumption of the part, e.g., the DAC can be powered down when a clock output\nis being generated. The AD9833 is available in a 10-lead MSOP packag. Control\nRegister The AD9833 contains a 16-bit control register that sets up the AD9833\nas the user wants to operate it. All control bits, except MODE, are sampled on\nthe internal negative edge of MCLK.Table II describes the individual bits of\nthe control register. The different functions and the various output options\nfrom the AD9833 are described in more detail in the section following Table\nII.To inform the AD9833 that the contents of the control register will be\naltered, D15 and D14 must be set to 0 as shown below. INTERFACING TO\nMICROPROCESSORS The AD9833 has a standard serial interface that allows the\npart to interface directly with several microprocessors. The device uses an\nexternal serial clock to write the data\/control information into the device.\nThe serial clock can have a frequency of 40 MHz maximum. The serial clock can\nbe continuous, or it can idle high or low between write operations. When\ndata\/control information is being written to the AD9833, FSYNC is taken low\nand is held low while the 16 bits of data are being written into the AD9833.\nThe FSYNC signal frames the 16 bits of information being loaded into the\nAD9833. AD9833 to ADSP-21xx Interface Figure 10 shows the serial interface\nbetween the AD9833 and the ADSP-21xx. The ADSP-21xx should be set up to\noperate in the SPORT transmit alternate framing mode (TFSW = 1). The ADSP-21xx\nis programmed through the SPORT control register and should be configured as\nfollows: Internal clock operation (ISCLK = 1)Active low framing (INVTFS =\n1)16-bit word length (SLEN = 15)Internal frame sync signal (ITFS = 1)Generate\na frame sync for each write (TFSR = 1) Transmission is initiated by writing a\nword to the Tx register after the SPORT has been enabled. The data is clocked\nout on each rising edge of the serial clock and clocked into the AD9833 on the\nSCLK falling edge.
