SY88927VZG is an integrated transceiver and voltage-level shifter built upon its patented low-voltage process technology. It has excellent performance in the face of external interference and is ideal for data communication applications. Unlike earlier integrated circuits of this type, the SY88927VZG is designed for data transmission over longer distances, in addition to providing very low power consumption and high noise immunity.

Application Fields

The SY88927VZG can be applied to many high speed communication standards such as USB, 2.5 Gbps Ethernet, Gigabit Ethernet, and RS-232, making it suitable for both PC applications and embedded systems. Due to its low power consumption, ultra-low-voltage operating range, and excellent signal integrity, the SY88927VZG is commonly used in on-board radio modems, GPS receivers, and communication interface cards. Additionally, its unique voltage-level shifter core makes it suitable for applications where consumers and producers use different power supplies.

Working Principle

The SY88927VZG is a voltage-level shifter and transceiver combining a multi-stage shift register and a differential buffer. Its input and output pins feature high levels of impedance and common-mode voltage range for the product. Depending on the selected standard, the voltage range between individual data terminal pins varies from 0.9 V to 5 V. The SY88927VZG dynamically adjusts the voltage levels of data transmissions between different circuits.

The core of the SY88927VZG contains a converter that changes the voltage level of the data signals sent to the receiver and a low noise amplifier to impede external interference from affecting the signals being sent. This integrated circuit further utilizes a shift register, which allows the device to automatically adjust the level of the incoming data signals to the input level of the receiver, eliminating the need for an external circuit to convert the signals\' voltage level.

Conclusion

The SY88927VZG integrated transceiver and voltage-level shifter is an advanced device suitable for data communication applications over longer distances, while still providing low power consumption and high noise immunity. This versatile device has a multitude of application fields, including PC applications, embedded systems, and on-board radio modems, and utilizes a multi-stage voltage-level shifter and low noise amplifier to protect against external interference.
