SP207ET-L/TR is a family of high performance, low power, differential line receivers designed to meet the requirements of modern high performance systems. The device has an integrated differential line receiver in an ultra-small package, making it ideal for applications in a variety of system designs.

SP207ET-L/TR is an ideal solution for applications such as data communications, clocks, peripheral components, serial communication, and controllers. It is designed to provide high speed data transmission capabilities without compromising power efficiency.

Application Field

SP207ET-L/TR is mainly used in a wide variety of data communications and clock applications. Its integrated differential line receiver makes it suitable for high speed data transmission and it is particularly useful in applications where low power consumption is critical. These include high performance computers and networking devices, digital audio/video devices, and embedded systems. It can also be used in automotive infotainment, medical, and industrial applications.

Working Principle

The SP207ET-L/TR operates on a differential input signal from a differential line driver. The differential line receiver is then converted to a logic output signal. The traditional line receiver has two inputs: a positive input and a negative input. The differential line receiver has two inputs as well – a positive input, a negative input and an output; this way, the voltage difference between the two inputs and the output is determined. The differential input signal can be correlated to the output of the device and the preferred output is the one where the greatest difference is shown.

In the SP207ET-L/TR, the differential line receiver uses an open-loop system to perform the task of detecting the differential line. In the open loop system, a single resistor is used to detect the differential line. The resistor has been divided into two differential paths, a positive and a negative path. The resistor values are determined by the line driver, usually 1000 Ohms. The components in each path have the same impedance but with opposite polarity. Depending on the input signal, the output of the device is determined. The device will detect the differential line when the input signal is greater than the reference voltage. The SP207ET-L/TR provides a power on reset function which ensures that the device operates with an initial startup state. When the device is powered on again, the device will detect the differential line again and the output of the device is determined.

The SP207ET-L/TR is suitable for applications with high noise immunity due to its on-chip termination resistors that provide a low EMI footprint. It also offers protection from spurious signals, because the device can detect any noise above the reference voltage and automatically shut down the circuit. Additionally, the device is immune to common mode interferences due to its differential output architecture. With its low power consumption, the SP207ET-L/TR is a great choice for applications that require low power consumption.

In conclusion, the SP207ET-L/TR is a versatile and reliable device that is suitable for a wide variety of applications. Its integrated differential line receiver makes it suitable for high speed data transmission and its low power consumption makes it ideal for applications that require low power consumption. Additionally, its resistance to interference and noise make it a great choice for applications with high noise immunity.
