SN65LVDS179DGKG4 is an integrated dual transceiver manufactured by Texas Instruments. It is a high-speed, low-power differential bus transceiver which meets the electrical PC99 and SFF-8472 (Short Wavelength SFP) requirements and is reputed for its low power consumption, higher speeds, and improved transmit snyc recovery. It is economical, reliable and effective when used in data communication applications.

The SN65LVDS179DGKG4 falls into the category of interface - drivers, receivers, and transceivers. It includes two transceivers that provide differential port configurations, and each transceiver incorporates data flow control logic to enable full-duplex communication into and out of the serial port. It is an LVDS (Low Voltage Differential Signaling) device and works at a voltage range of 3.3 V. It cuts down on power consumption and noise, and enhances signal disharge rate for reliable communication. It also features a common mode noise rejection of -10 V and a maximum data rate of 1.41 Gbps over a maximum distance of 15 m.

The SN65LVDS179DGKG4 combines transmitter and receiver. The transmitters may be used to convert LVCMOS/LVTTL inputs to LVDS outputs, while the receivers can be used to treat LVDS inputs to LVCMOS/LVTTL outputs. The line rate of the transceiver is programmable of up to 1.41 Gbps, which enables new applications for serial data transmission over board-to-board and backplane communications. The device can dissipate 1.3 W of power, demonstrating heat resistance and power efficiency.

The working principle of the SN65LVDS179DGKG4 is simple yet efficient. Its receiver uses a current steering technique which compares the receiver inputs differential voltage with an internal reference voltage. The differential input voltage is then converted into a single-ended digital high or low voltage.The transmitter provides open-drain output with current source loads. The receiver and output are active-low, enabling seamless connection with industry standard open collector ICs.

The device allows for two operating modes - LVDS Mode and AC Coupled Mode. In LVDS Mode, the device is used as an LVDS transceiver. In AC Coupled Mode, the device can be used to drive and receive AC coupled signals. This allows the device to be connected to the oscilloscope and allows for debugging connections. This dedicated low-power SMBus-programmable transceiver is suitable for wide range of applications such as MPEG4 for DVD players, disk drivers, and High Definition TeleVision (HDTV).

In conclusion, SN65LVDS179DGKG4 is a high-speed, low-power differential bus transceiver manufactured by Texas Instruments. It falls into the category of interface - drivers, receivers and transceivers, and features two transceivers that provide differential data flow control logic for reliable communication. It works at a voltage range of 3.3 V, with a common mode noise rejection of -10 V and a maximum data rate of 1.41 Gbps over a maximum distance of 15 m. It is economical, reliable and effective when used in data communication applications unlike any other device in the market.
