This Product Selection Guide contains information to help select products in the DSP (Digital Signal Processors) category on DigiKey.com
Digital signal processors are devices similar to microprocessors or microcontrollers, but distinguished by having internal architectures that are adapted for the continuous execution of algorithms dominated by multiplication and addition operations performed on a continuous stream of data, as contrasted with algorithms that are dominated by conditional logic or a multiplicity of concurrent processes. They are commonly used in applications such as audio or video signal processing.
SelectionCharacteristics
Type: Indicates the style and configuration of the device.
Interface: Indication of which interface(s) or protocol(s) are used by the device to communicate with other components in the system.
Clock Rate: Indicates maximum rated operating frequency of processor core.
Non-Volatile Memory: Indicates the amount and type of Non-Volatile Memory being used in the item.
On-Chip RAM: Indicates the amount of On-Chip RAM memory the item has.
Voltage - I/O: Characterizes the supply voltage range over which a device’s external interface functions are specified to operate.
Voltage - Core: The nominal supply voltage required for a processor’s internal logic functions.
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 to go by this terminology when designing your circuit.
