Telecom

This Product Selection Guide contains information to help select products in the Telecom category on DigiKey.com

Telecom interface integrated circuits (ICs) provide specific functionality and control in communication network interfacing such as Ethernet switching, line drivers, ISDN, amplifiers, channel extenders, digital phase-locked loops, DTMF, tone generators and decoders, echo cancelation, detectors and generators, DDA, phone line monitors, and calling line identifiers.


SelectionCharacteristics

Function: Indicates the device’s primary purpose within a circuit.

Interface: Indication of which interface(s) or protocol(s) are used by the device to communicate with other components in the system.

Number of Circuits: Indicates the number of circuits of similar functions that are implemented within the device.

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.

Current - Supply: This represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.

Power (Watts): Typically this represents the maximum power rating to which a device will meet its given specifications. Exceeding this power rating 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 to go by this terminology when designing your circuit.
