MAX14883EASA+T

MAX14883EASA+T is an integrated interface IC designed to convert EASA high-speed serial differential signals into LVDS signal formats, making it compatible for use on FPGAs, ASICs, and other processors. The MAX14883EASA+T requires minimal power, operates at low signal frequencies, and is suitable for ruggedized applications. This IC is ideal for applications such as automotive audio, hard disk drive (HDD) encoding, and communications in the aerospace industry.

The MAX14883EASA+T is a slight upgrade of the original MAX14883EASA but with the addition of a differential / single end-end termination circuit. This terminates the line when needed, helping to reduce overall power usage and suppress unwanted noise due to possible reflections on the line. The MAX14883EASA+T has an integrated thermal sensing circuit, which allows temperature measurement in the die and also monitors the supply voltage.

The main purpose of the MAX14883EASA+T is to convert the high-speed serial differential signals from devices such as FPGAs or ASICs into LVDS signal formats. The MAX14883EASA+T is a single-chip solution for converting the differential signal into LVDS, allowing for the use of FPGAs and other ICs on a single board design. This simplifies the board layout compared to a two-chip solution of an EASA converter and an LVDS transceiver.

The MAX14883EASA+T integrates a programmable termination resistor network, allowing the user to set the TVIST and TVRM termination voltage levels to the desired range. This helps reduce the noise caused by unwanted reflections and maintains the integrity of the transmitted data. The TVIST is the input threshold voltage while the TVRM is the output common-mode voltage.

To convert the differential signals from devices such as FPGAs or ASICs to LVDS, the MAX14883EASA+T relies on a pulse transformer. This transformer allows for the transmission of the data signals without degradation, such as due to noise or crosstalk. When the simplex DS and DFS signals are received by the MAX14883EASA+T, the differential / single ended termination circuit terminates the line on both ends and then sends the LVDS data signals downstream.

The MAX14883EASA+T is ideal for applications that require low-power operation and minimal external components. The integrated circuit only requires a few external components, such as a termination resistor and a termination capacitor, making it ideal for battery-powered applications and applications in compact form factors. The MAX14883EASA+T is also suitable for ruggedized applications such as automotive audio and HDD encoding.

In summary, the MAX14883EASA+T is an ideal solution for applications requiring a cost-effective, low-power and low-noise EASA-to-LVDS conversion. Its integrated termination circuitry helps reduce power usage and suppress unwanted reflections, and its simplex terminations send the LVDS data without degradation of the signal. The MAX14883EASA+T is suitable for ruggedized applications as well as low-power, battery-powered applications.
