This Product Selection Guide contains information to help select products in the Modems - ICs and Modules category on DigiKey.com
Interface Modem ICs and Modules are devices that modulate or demodulate an incoming signals from a telephone or cable lines to be transmitted from a computer. The data format is ASK, FSK, Bell 202, HART, V.21, V.22, V.23, V.32, V.34, V.90, and V.92 with Baud rates of selectable, 300, 1.2k, 1.8k, 2.4k, 4.8k, 9.6k, 14.4k, 19.2k, 20k, 33.6k, 38.4k, 56k, and 200k having a mounting type of socket, surface mount, or through hole.
SelectionCharacteristics
Data Format: Indicates the basic set(s) of connection standards supported by a device; has implications for achievable data transfer rates.
Baud Rates: Indicates the rate at which the number of signal elements or changes to the signal occurs per second when it passes through a transmission medium
Voltage - Supply: Typically this rating indicates the nominal amount of voltage you would expect the device to draw during normal operation.
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.
