The 74LX1G70CTR is a low-power, high-speed \'low-swing\' differential-input/differential-output transceiver designed for use in point-to-point links. It belongs to a range of Logic - Buffers, Drivers, Receivers, Transceivers and is designed for operation in 2.5 Volt (V) and 3.3 V systems. This device can convert single-ended source voltage output from the logic family (LS, LV and HSTL compatible) into the low-swing differential output signals. The device can transmit data at a peak data rate of 1Gbps. It has been optimized for applications that require low power and low-skew, such as data links, and fire wire and multimedia applications.

As a member of the Logic family, the 74LX1G70CTR consists of two separate differential transmitter and receiver sections, each with their own input and output pins. For example, Transmitter (T1) consists of inputs E1, F1, G1 and outputs T1, U1. Likewise, Receiver (R1) consists of inputs T1, U1, V1 and outputs E1, F1, G1. Each section is capable of supporting data rates of up to 800 Mbps with a low noise and low-skew environment.

The operation of the 74LX1G70CTR can be split into two parts. The transmitting part of the device converts fan-out of the logic family source output signal into three different low-swing differential signals. The receiver part then converts those signals into three-state output of the logic family for correct transmission of data.

The core of the device is the low-swing signal converter circuit. The signal converter of the 74LX1G70CTR has two high-speed differential pairs, a low-noise galvanic voltage isolator, a bandgap reference and a temperature-compensating circuit. This signal converter is essentially an adaptor circuit between logic output pins and differential-pair inputs of the transceiver.

The 74LX1G70CTR also has a programmable logic unit that allows for user-defined codes for different types of data transmissions. Additionally, the 74LX1G70CTR has built-in protection functions that avoid ESD and over current damage. The device also features Automatic Restoration, an important feature that allows it to recover in the event of an unexpected failure.

The 74LX1G70CTR is well suited for many applications, including data links, fire wires, and multimedia. It is highly reliable and efficient, with low power consumption and a high suppression of EMI/RFI interference. It is an attractive choice when dealing with applications that require low-power, low-skew, and high speed performance. It is a valuable addition to the Logic family.
