Introduction

The 74AUP1G125GN,132 is a single bidirectional 1-channel or dual bidirectional 2-channel noninverting, field-programmable gate array (FPGA)-compatible, low-voltage differential signaling (LVDS) and low-voltage positive emitter coupled logic (LVPECL) transceiver. It is designed for applications requiring ultra-low-power LVDS or low-power LVPECL signal transfer. The 74AUP1G125GN,132 is designed to meet the requirements for a variety of applications in networking, telecommunications, and other low-voltage applications.

Features

The 74AUP1G125GN,132 features the following:

• Ultra-low power consumption: 420 mW (typical) per channel when powered from a single 3-V supply
• 200 Mb/s LVDS data rate per channel in narrow-bus mode
• 400 Mb/s LVDS data rate per channel in wide-bus mode
• Dual-channel operation for LVPECL signals at up to 650 MHz in common-mode operation
• Single- or dual-channel operation for LVDS signals
• Logic-low initialization option
• LVDS and LVPECL common-mode operation
• Fully-functional, pin-compatible LVDS and LVPECL version
• Compatible with FPGA devices
• Built-in self-test (BIST) capability
• Integrated ESD protection

Applications

The 74AUP1G125GN,132 is suitable for a wide range of applications requiring high-speed LVDS and LVPECL signaling. It is well-suited for consumer electronics, computer systems, interface communication systems, product design, data acquisition, and mixed-signal audio applications.

Working Principle

The 74AUP1G125GN,132 transceiver works like any other LVDS or LVPECL transceiver. However, its design makes it especially suitable for applications that require ultra-low-power yet reliable LVDS or low-power LVPECL signal transfer. The transceiver has two dual-channel LVDS transmission lines, one bidirectional LVPECL transmission line, and one dual-channel LVDS reception line. The LVDS transmission lines transmit digital data from the transmitting end to the receiving end and the LVPECL line is used for communication between the two ends. The dual-channel LVDS reception line is used for receiving digital data from the receiving end. The transceiver has a built-in self-test (BIST) capability for testing the functionality of each line.

Conclusion

The 74AUP1G125GN,132 is a single bidirectional/dual bidirectional non-inverting, field-programmable gate array (FPGA)-compatible, low-voltage differential signaling (LVDS) and low-voltage positive emitter coupled logic (LVPECL) transceiver. It supports a variety of communication applications in consumer electronics, computer systems, interface communication systems, product design, data acquisition, and mixed-signal audio applications. Its ultra-low power consumption, high speed, and reliable signal transfer make it the ideal choice for applications requiring ultra-low-power LVDS or low-power LVPECL signaling.
