The SN65LVDS3487D is a triple transmitter and receiver pair that is distributed by Texas Instruments, suitable for applications such as high-speed point-to-point data transfers. It supports most data rates common to many serial communications standards like USB, FireWire, and LVDS while utilizing the Low-Voltage Differential Signaling (LVDS) protocol. The SN65LVDS3487D triple driver and receiver pair, with its fast data rates, low power consumption, and small component size make it an ideal physical layer component for many commercial and industrial applications.

The SN65LVDS3487D consists of a transmitter with differential outputs, a receiver with differential inputs, and an invertor for Level Translation. The transmitter component interpretes a single-ended input CMOS logic signal and converts it into a differential signal capable of transmitting information over distances of up to 50 meters at data rates up to 100Mbps (100Mbit/second). The differential signal is sent over a pair of LVDS-compliant twisted-pair shielded copper cables. A false-ground plane configuration is also supported.

The receiver component interpretes an incoming differential signal and converts it back into a single-ended CMOS logig signal for further processing. The receiver features external positive enabling and input hysteresis for noise rejection and optimum power performance.

For Level Translation from diffrent voltage domains, the SN65LVDS3487D also provides an integrated invertor that inputs a single-ended low voltage logic signal and outputs a voltage-inverted version of that signal. The invertor function can be enabled by tying the VCC_IN pin directly to the VCC_OUT pin.

The SN65LVDS3487D provides superior data processing capabilities in extreme conditions. The device has a common mode voltage range of ±5V, which covers most industrial and commercial applications. The integrated power supply filters reduce noise distortion and allow the device to operate with lower common mode voltages.

In terms of physical size, the SN65LVDS3487D occupies very little space on a printed circuit board with a package size of only 4.4mm x 5.0mm, giving it a distinct advantage over other components for minimum envelope size applications. Additionally, its low supply voltage of 3.3V and 45mA supply current can greatly reduce system power consumption.

In summary, the SN65LVDS3487D triple transmitter and receiver pair is ideally suited for applications that require high speed, low power consumption and a small physical size, such as USB, FireWire and LVDS interfaces. The device’s fast data rate, low power consumption and small size give it the advantage over other components in minimal envelope size applications. Additionally, its high common mode voltage range, power supply filtering, and low supply voltage and current give it unrivaled performance in extreme conditions.
