SN65LVDS349PW application field and working principleIntroductionThe SN65LVDS349PW is an interface device that is designed to be used in applications that require high speed data. It provides a data bidirectional communication interface between a host system and peripheral devices, such as LCD monitors and hard disk drives. This device has one of the lowest power consumption levels in the market, resulting in a higher system integration performance and increased operating efficiency. The SN65LVDS349PW is a small, low-power integrated circuit that is divided into two main sections; the driver and receiver section. The driver section includes features such as level translators, transmitters, and encoders. The receiver section includes features such as level shifters, receivers, and decoders. This application note will discuss the various features of the SN65LVDS349PW and its application field.Features• Low Power: The SN65LVDS349PW provides an operating voltage range of 2.4V to 3.6V with minimum power consumption for efficient system integration.• Configurable data transmission logic: The SN65LVDS349PW supports a host selection logic that can be configured for different types of transmission logic such as fast (3.3V) logic or LVDS logic.• Level Translator: The SN65LVDS349PW includes a level translator to facilitate communication between the 1.2V and 3.3V signals. This level translator is capable of translating output signals up to 1.2V to 3.3V and vice versa.• Flexible Communication Interface: The SN65LVDS349PW supports a number of communication interfaces such as serial, parallel, or even mixed.• High Speed Data Communication: The SN65LVDS349PW is designed to provide high speed data communication, with data rates up to 800 Mbps.• Data Multiplexing: The SN65LVDS349PW supports up to sixteen data multiplexing, accommodating up to eight data lanes in each direction.• Small Package Options: The SN65LVDS349PW is offered in small packages such as SOIC, SSOP, and VQFN.Application FieldThe SN65LVDS349PW is ideal for applications that require high speed data communication, such as LCD monitors, hard disk drives, and multimedia displays. It can also be used in applications that require level translating between 1.2V and 3.3V signals, such as memory modules and embedded systems. The small package options offered make it suitable for applications with space constraints.Working PrincipleThe SN65LVDS349PW is a two-part device. The driver section includes a Level Translator and Transmitter, and the receiver section includes a Level Shifter and Receiver. The Level Translator acts as a bridge between the input signals of 1.2V and 3.3V. It can convert the output signals up to 1.2V to 3.3V and vice versa. The transmitter encodes the input data and transmits it to the Level Shifter. The Level Shifter then shifts the data between 1.2V and 3.3V levels. The receiver then decodes the transmitted data and provides the output at the Level Shifter.The SN65LVDS349PW is also equipped with configurable logic that allows the user to configure the logic used to transfer data. This configurable logic supports various transmission logic options, such as fast (3.3V) logic or LVDS logic. Furthermore, the SN65LVDS349PW supports multiple data multiplexing, accommodating up to eight data lanes in each direction. The transmitter and receiver are synchronized, allowing for fast and reliable data communication.ConclusionThe SN65LVDS349PW is a low-power, multi-functional interface device that is suitable for applications that require high speed data communication. It is equipped with features such as low power, a configurable data transmission logic, level translator, flexible communication interface, high speed data communication, small package options, and data multiplexing. The SN65LVDS349PW is suitable for applications such as LCD monitors, hard disk drives, and embedded systems. Its Level Translator, Transmitter, Level Shifter, and Receiver make it suitable for applications that require level translating between 1.2V and 3.3V signals. Its configurable logic allows the user to choose which transmission logic to use, and its multiple data multiplexing capability provides efficient data communication.
