MAX3094ECSE Application Field and Working Principle

The MAX3094ECSE is a high-performance, low-power differential receiver/transceiver designed for operation in personal computer system, peripheral and other communication interface applications. It’s intended to be used in systems that interface with a wide range of PC suppliers’ products, including ISA, PCI, AGP, USB and FireWire applications. This differential receiver/transceiver is implemented in a single-ended to differential transformer design, with a differential input stage controlled by the receiver output current. The output of the MAX3094ECSE is a 3.3-V CMOS compatible digital signal and it can be operated from a single 1.5-V to 3.3-V supply.

The MAX3094ECSE differential receiver/transceiver is designed for operation in applications up to 3.3 Mbps and can be used in point-to-point or multi-drop systems. The device features low power operation, low noise floor and excellent EMI performance, which make it ideal for a variety of system-level applications. The differential receiver/transceiver also features an integrated low voltage low EMI power supply, allowing it to operate over a wide range of system bus voltages and conditions. The fully integrated architecture eliminates the need for additional system level components, resulting in lower power consumption, smaller board area and reduced board complexity. The MAX3094ECSE is RoHS compliant and includes:

• Integrated low noise differential receiver/transceiver
• Low voltage operation
• Low EMI power supply
• Optimized EMI performance
• Dual 3.3V CMOS compatible digital outputs

The MAX3094ECSE is well suited for applications that require high performance and low power solutions. It is ideal for point-to-point and multi-drop system level interfaces, as well as differentiating signals between PCIe v2.1 and 3.0 for high speed serial switching applications. The device is also well suited for UHS-II mobile applications, allowing for the simultaneous integration of voltage, clock and data with up to 4 receivers per receiver/transceiver.

Working Principle

The MAX3094ECSE differential receiver/transceiver is based on a transformer-coupled design. It includes an integrated low voltage power supply and two power supply pins. The two power supply pins are used to control the differential input and output stages of the device. The input stage of the device is based on a single-ended to differential amplifier architecture. The input differential amplifier controls the voltage swing of the receiver output current. The output stage of the device is based on a CMOS-compatible, 3.3 V output stage, which is controlled by the receiver output current.

The device includes two digital outputs (A and B), which are used to control the differential output stage. The device also includes a clock output (CK), which is used to provide synchronous operation of the digital outputs. The device also includes a power regulation circuit, which ensures compliance with the output voltage requirement. The device also includes an integrated, low EMI power supply to limit the amount of EMI generated by the circuit, ensuring EMI performance of the system.

The MAX3094ECSE differential receiver/transceiver also includes a separate digital control port, which is used to provide test control signals, such as an input signal check, reset and suspend. This port can also be used to control the output current of the device, allowing for the optimization of the system power consumption.
