LTC2874IUHF

The LTC2874IUHF is a dual-channel, differential, high-speed LVDS transceiver. It integrates two identical transmitters and two identical receivers into a single 28-pin LQFN package. The LTC2874IUHF is designed to operate on either single 3.3V supply or dual distanced 3.3V/2.5V supplies. It can be used for differential channel rate up to 1.6 Gbps. The programmable I/O input levels allow it to be used with 3.3V, 2.5V, and 1.8V logic families.

The LTC2874IUHF is an especially useful device in applications that involve sending and receiving high-speed, low power, and low cost signals. Typical applications include lighting control, video processing, and communication systems. The LTC2874IUHF’s low power consumption make it ideal for application in such areas where power consumption and cost are a major concern. It is especially suitable for use with the new generation of high-speed serial links.

Working Principle

The LTC2874IUHF is an integrated, differential, high-speed LVDS transceiver. It operates from a single 3.3V or dual distanced 3.3V/2.5V power supply and is designed to support data rates up to 1.6 Gbps per channel. The LTC2874IUHF integrates two transmitters and two receivers with each transmitter having two independent differential outputs. Each transmitter output is 2.8V min-to-min, while the receiver input is 3.2V max-min. The LTC2874IUHF also features common mode output control (CMO), programmable logic voltages, and power-down protection.

The LTC2874IUHF uses a differential signaling scheme with two separate wires for each channel. One wire carries the data signal while the other carries the inverted signal. The two signals travel over the same physical medium and their combined effect is used to reduce noise and interference. The LTC2874IUHF also features common mode output control (CMO) for added signal integrity. The CMO allows the user to adjust the common mode voltage of the overall link to a level that is optimal for the particular application.

The LTC2874IUHF is designed to provide low power consumption and cost effective performance. It is capable of auto-detection of signal polarities, output swing adjustment, power-down protection and data scrambling for enhanced signal integrity and noise immunity. The programmable I/O input levels allow the device to be used with 3.3V, 2.5V and 1.8V logic families.

Conclusion

The LTC2874IUHF is a dual-channel, differential, high-speed LVDS transceiver. Its low power consumption and reliable performance makes it an ideal device for applications involving high-speed, low-power, and cost-effective signal transmission. The integrated features such as common mode output control (CMO), programmable logic voltages, and power-down protection, make the LTC2874IUHF an especially attractive device for system designers looking for a balance of performance, power, and cost.
