The DS92LV18TVV/NOPB is a low-voltage transceiver chip falling under the category of serializers, deserializers and other interfaces. The chip has been designed to provide a high-speed physical link between a host and a peripheral device, as well as other similar high-speed links.

Application Field

The DS92LV18TVV/NOPB chip is designed for the Serial ATA (Serial Advanced Technology Attachment) version 7.0 interface. It is most suitable for connecting computers, hard drives, and other storage devices. The DS92LV18TVV/NOPB can also be used as a SATA switch to extend the SATA interface to more than one device. It can also be used to connect a microcontroller to a downstream device, supporting up to 8 lanes of high-speed transmission.

Working Principle

The DS92LV18TVV/NOPB chip is designed to offer a variety of features in terms of data transfer. It functions as a serializer/deserializer, meaning it takes in serial data and converts it into parallel data, before sending it further. The chip also has a separate receiver circuit with its own serial-to-parallel data conversion, depending on the application. The chip supports a range of transmission standards, such as 1.5 Gb/s, 3 Gb/s, 6 Gb/s and 12 Gb/s. It comes with two power saving modes, power saving mode and sleep mode. In power saving mode, the chip can reduce its data transfer rate to 0.5 Gb/s. The chip also supports spread-spectrum clocking, allowing the user to reduce EMI (electromagnetic interference) emissions.The chip also supports differential voltage levels, supporting both 1.2 V and 1.5 V logic levels. The integrated comparators simplify the implementation of data recovery and equalization when using low-voltage logic. The device may also be configured as a retimer, removing jitter and reducing electromagnetic interference issues. The chip is also designed with attenuation capability, which enables the user to tailor the differential output voltage, enabling precise control of transmit eye diagram parameters.

Overall, the DS92LV18TVV/NOPB chip is an excellent choice for connecting computers and other peripherals, and for supporting the Serial ATA version 7.0 interface. The chip simplifies the implementation process, with its wide range of features designed to reduce EMI and attenuation issues. It is also designed to reduce power consumption and to offer a low-voltage logic level requirement.
