MAX3632ETG+ is a special purpose line amplifier from Texas Instruments, designed to work in low-voltage systems. This high performance line driver is a two-channel amplifier optimized for operation in Low-Voltage Differential Signaling (LVDS) applications.The MAX3632ETG+ features a low operating voltage from 0.9V to 3V and excellent power-supply rejection ratio (PSRR). The amplifier also offers a low power consumption of only 1mA and an output swing of approximately 800mV for low power delivery losses. Additionally, the MAX3632ETG+ features excellent common-mode range, providing linear operation over a wide common-mode input range. As such, it is suitable for demanding applications, such as using long data cables.The MAX3632ETG+ is optimized for low-noise applications and has low output noise, with typically 1.5mV total output noise spectral density. It offers excellent dynamic performance and 10ps of skew delay between outputs.The application field of the MAX3632ETG+ covers a wide range and applications, such as point-to-point communication and backplane data transmission, in which low power consumption, low common-mode noise, low output noise, and excellent PSRR are mandatory requirements. However, due to its relatively high switch rate, the MAX3632ETG+ does not perform well in high-speed operation applications.The MAX3632ETG+ has two identical low-voltage line drivers that feature two differential input and two differential output drivers. Each driver has a single-ended input and three single-ended outputs. The device has two dedicated input pins, which can be used to switch between two different input sources. Furthermore, the MAX3632ETG+ contains an output pre-emphasis network and a differential-to-differential output termination network, which improves the common-mode noise performance.The operating principle of the MAX3632ETG+ is based on the principles of differential signaling. It works by converting a single-ended input signal into a differential signal, allowing the transmission of the signal over a twisted pair cable with minimal losses. The device then amplifies the differential signal and eliminates any noise or distortion caused by the transmission medium. The differential output of the amplifier is then converted back into a single-ended signal, which can be transmitted over a single-ended transmission line.The MAX3632ETG+ also features calibration capability, which allows the user to set any level of pre-emphasis and to adjust the output levels for optimal performance. Additionally, the dual-channel output features a common-mode output range and output impedance balance control, which enables the operation of the device in a wide variety of LVDS applications.In conclusion, the MAX3632ETG+ is an ideal line driver for low-voltage differential signaling applications, such as point-to-point communication and backplane data transmission. It features low power consumption, low output noise, and excellent PSRR. Additionally, the device has calibration capabilities, which allows it to be used in a wide variety of LVDS applications.
