20 mW Power, 2.3 V to 5.5 V, AD9834 Data Sheet

When voltages greater than that specified for the output compliance are generated, the AD may not meet the specifications listed in the data sheet. To load the remaining eight bits to the AD, P3. The device operates with a power supply from 2.

The Sample button will be displayed if a model is available for web samples. This square wave can also be divided by two before being output. Datasheet first two bits of each bit word define the frequency register the word is loaded to and should, therefore, be the same for both of the consecutive writes.

When data is to be transmitted to the AD, P3. The output frequency accuracy and phase noise are determined by this clock.

This control bit indicates whether the 14 bits being loaded are being transferred to the 14 MSBs or 14 LSBs of the addressed frequency register. Evaluation Boards Pricing displayed is based on 1-piece.

Universal Changes to Features Section We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing datzsheet as well. The main component of the NCO is a bit phase accumulator. SCLK should idle high between the two write operations.

The power supply lines to the AD should use as large a track as possible to provide low impedance paths and reduce the effects of glitches on the power supply line. If the user wants to alter the entire contents of a frequency register, two consecutive writes to the same address must be performed because the frequency registers are 28 bits wide. Model Package Pins Temp. These registers contain invalid data, and, therefore, should be set to a known value by the user.

20 mW Power, V to V, AD Data Sheet

Knowing that the phase of a sine wave is linear and given a reference interval clock periodthe phase rotation for that period can be determined.

These modulation schemes are fully implemented in the digital domain, allowing accurate and simple realization of complex modulation algorithms using DSP techniques. At least one model within this product family is in production and available for purchase. Pricing displayed is based on 1-piece.


Therefore, they also have a latency associated with them. The endpoints of the transfer function are zero scale, a point 0. The SFDR refers to the largest spur or harmonic present in the band of interest. The internal circuitry of the AD consists of the following main sections: The timing diagram for this operation is given in Figure 5.

Operating temperature range is as follows: Proper operation of the comparator requires good layout strategy. Both of these supplies can have a value of 2. It is necessary only to have sufficient phase resolution such that the errors due to truncation are smaller than the resolution of the bit DAC.

These are described in Table 7. For example, the DAC can be powered down when a clock output is being generated. Pin Configuration Table 4. Phase Offset Register 1. International prices may differ due to local duties, datqsheet, fees and exchange rates.

It is important to note the datashdet dock date on the order entry screen.
