Introduction

The DS90LV048ATMTCX is a low voltage differential signaling (LVDS) transceiver designed to reduce EMI emission in high-speed data transmission applications. It is used as an interface between LVDS and other communication bus systems such as parallel Video Digital (VDO), TTL, CMOS and general-purpose I/O interfaces, allowing up to four digital data streams to be transmitted and received over a pair of LVDS lines. It supports both point-to-point and multi-point architectures and is compliant with the ANSI/TIA/EIA-644-A LVDS standard.

Application Field

The DS90LV048ATMTCX is ideal for a wide range of applications, such as high-speed data transmission between two or more devices. It is suitable for use in a variety of systems, such as portable medical systems, transportation displays, medical displays, instrumentation, andindustrial control systems. It is also suitable for applications requiring full-duplex serial communications, such as wireless base stations, imaging systems, and display control systems.

Working Principle

The DS90LV048ATMTCX is designed to transmit and receive digital data at speeds up to 25 MHz. It employs a differential line driver and receiver in each direction, with a data rate that is selectable via serial programming. The transmitter section consists of four high-speed LVDS drivers, each capable of carrying a full-speed 25 MHz signal. These drivers are powered by a single 3.3V supply and can support a data rate up to 10 Mbps. The receiver section consists of four 165 mV (typical) receivers with a common-mode input range of -2.25V to 3.45 V. The receivers operate from a single 3.3V supply and can support data rates up to 25 Mbps.The DS90LV048ATMTCX converts the signal from the user data bus receiving lines into LVDS compatible signal levels. The signal from the LVDS bus is then regenerated back to the original signal for transmission on the user data bus. The transceiver is capable of transmiting/receiving four single-ended LVDS signals, or two full-duplex LVDS signals.A ultra-low jitter differential clock signal is generated internally, which is used to synchronize the drivers and receivers. The jitter is attenuated to 10 ps RMS (maximum) over an operating temperature range of -40°C to 85°C. The DS90LV048ATMTCX also features a wide common-mode range, allowing it to be used in applications with high common-mode voltages.

Conclusion

The DS90LV048ATMTCX is an ideal low voltage differential signaling (LVDS) transceiver for interfacing high-speed data between two or more devices. It offers a high data rate of up to 25 MHz, and is suitable for both point-to-point and multi-point architectures. The transceiver offers a low jitter, wide common-mode range, low power consumption, and wide operating temperature range, making it ideal for a variety of applications.
