Dual Potentiometer
The DS1845 dual potentiometer with nonvolatile memory is the first potentiometer with integrated memory specifically designed to enhance performance in gigabit transceiver modules
N/Adual potentiometer with nonvolatile memory is the first potentiometer with integrated memory specifically designed to enhance performance in gigabit transceiver modules. The device combines two linear-taper potentiometers with 256 bytes EEPROM, which provides nonvolatile storage for potentiometer output and configuration settings, and in-circuit programmability via a 2-wire interface.
The user configures the DS1845's dual 100-position and 256-position outputs with application-specific settings, which are maintained in nonvolatile memory and used in operation. The DS1845's interface allows drop-in compatibility with existing software written for standard 2-wire EEPROM, as well as in-circuit updates.
The optical transceiver module can be plugged externally into an electrical backplane in routers and networking hubs or soldered to a motherboard in a server.
