This Product Selection Guide contains information to help select products in the Direct Digital Synthesis (DDS) category on DigiKey.com
Direct Digital Synthesis (DDS) is used to produce analog waveforms of different frequencies from a digital signal. It is used for frequency control in wireless systems that must sweep across a wide range. The master frequencies clocks are 5MHz, 16MHz, 16.776MHz, 25MHz, 50MHz, 75MHz, 125MHz, 180MHz, 200MHz, 250MHz, 300MHz, 400MHz, 500MHz, 1GHz, 2.5GHz, and 3GHz with a resolution of 10 b, 12 b, or 14 b.
SelectionCharacteristics
Resolution (Bits): The length of the digital word used by a device to represent a continuously variable physical quantity.
Master fclk: The maximum usable clock input frequency, as defined by the manufacturer.
Tuning Word Width (Bits): The width of the data word that controls output frequency.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than use this terminology when designing your circuit.
