The MAX13086EESD+ is a line driver/receiver and transceiver that supports full-duplex, half-duplex, and four-wire serial communications. This device is designed to work quickly, with high speed data rates of 3.2–5.5 Mbps, making it the ideal choice for many applications. In this article, we will discuss the application field and working principle of the MAX13086EESD+.

Application Field

The MAX13086EESD+ is designed to work with serial data applications that require low power, low pin count and/or low EMI emission. These applications include:

• Consumer Electronics
• Automotive
• Industrial
• Medical
• Network Communications Equipment
• Data Transfer/Disk Drives

The MAX13086EESD+ is an ideal choice for these applications because of its small footprint and ability to support data rates of up to 5.5 Mbps. The device also features an integrated return path, which helps reduce EMI emission, as well as power-saving functionalities, such as low standby current (<1 μA).

Working Principle

The MAX13086EESD+ consists of a line driver, a line receiver, and a transmit/receive transceiver. The line driver is responsible for transmitting data, while the line receiver is responsible for receiving data. The transceiver is responsible for switching the device between the transmission and reception states.

The line driver consists of a differential amplifier and a level shifter, which converts the input signal (CMOS or TTL levels) to the differential voltage levels required by the line. The line driver has a selectable open-drain or push-pull output driver, that can be used to drive the line with any voltage levels that are compatible with the receiver.

The line receiver consists of a differential amplifier and a level shifter, which converts the differential voltage levels from the line to the CMOS or TTL levels that the device can understand. The receiver also has an adjustable comparator, which compares the Amplitude (AML) and Phase (PIM) of the incoming signal with reference voltages, allowing the device to detect any transmission errors.

The transceiver is responsible for switching the device between transmission and reception states. This is done using a dual-hysteresis circuit, which keeps the device in either the transmission (Tx) or reception (Rx) state, until a pre-defined input or output voltage is detected. When this voltage is detected, the device automatically switches to the opposite state.

The MAX13086EESD+ device is a highly versatile and efficient solution for serial data applications that require low power and/or low EMI emission. With its integrated line driver, line receiver, and transceiver, as well as its adjustable supply voltage and adjustable input/output voltage levels, the MAX13086EESD+ is the ideal choice for many applications.
