DS90LV048ATM/NOPB is a low-voltage differential signaling (LVDS) quad non-inverting Receiver. LVDS is an interface technology used to transmit data over twin-axial cables at very high speeds, and is often used in consumer electronics products and data communication applications.

It is implemented in low voltage (typically 3.3V) CMOS logic levels and can support arithmetic transmission speeds of up to 400 Mbps. Its simple interface supports easier transmission, which is often coupled with lower cost cables (twinax, ribbon) and a smaller form factor.

The DS90LV048ATM/NOPB is designed and tested to operate at (−40 to 85°C) temperature range, making it ideal for use in applications and products exposed to wide temperature changes. It is offered in SOIC-14 package, and features high output data rate of 300 Mbps and operating temperature range of 0 to 70°C.

Application Field

The DS90LV048ATM/NOPB is a ideal solution for driving full-speed and low-speed LVDS displays. It can be used in a variety of medical devices, military and aerospace applications, instrumentation and communications systems, industrial, automotive and consumer electronic applications.

It is also suitable for advanced television designs, HDTV monitors, LCDs, and projectors, as well as other applications requiring short-range point-to-point communication. Due to its low power consumption and capability to support high signal integrity, the DS90LV048ATM/NOPB can be used for multiple applications, such as computer system-level data interfaces and long-haul applications.

Working Principle

The DS90LV048ATM/NOPB is composed of four independent non-inverting LVDS receivers in a single SOIC-14 package. It integrates several features such as balanced driver/receiver operations, on-chip termination and eye-diagram enhancement. Each receiver has an output driver terminated internally through a 100 ohm resistor.

It is capable of transmitting up to four bits per channel at a data rate of up to 400 Mbps. The device has a differential input sensitivity of approximately one lh differential and a single-ended input sensitivity of approximately one lh single ended. It also offers an external enable control logic which is used to enable or disable one or more receivers.

The input signal is applied through the differential RXEN input, which is internally driven. The LVDS differential receiver will convert the input analog signal into a digital output waveform. The outputs of the receiver are high-impedance outputs and should be connected to the corresponding pull-up device.

The output of the LVDS receiver is a balanced, low-skew two-level signal that is used to maintain high output levels with low jitter. Moreover, due to its high-speed operation, the receivers are immune to noise and can operate at high data rates while maintaining low power consumption.

Conclusion

The DS90LV048ATM/NOPB is a quad non-inverting LVDS Receiver with very low power consumption and a high output data rate of up to 400 Mbps. It is ideal for driving full-speed and low-speed LVDS displays, and can be used in medical, military, industrial, automotive, and consumer electronic applications. The receiver features on-chip termination, eye-diagram enhancement, internal 100 ohm pull-up termination, and high signal integrity. The device can be used for multiple applications such as computer system-level data interface and long-haul applications.
