Introduction to SN65LVDS301ZQE

The SN65LVDS301ZQE is an integrated serializer/deserializer (SerDes) device that simplifies the design of high-speed serial links. It consists of four sections: an integrated data rate controller, an 8-bit input data shift register, an 8-bit output data shift register and an integrated multiplexer. It supports data rates up to 8 Gb/s and provides an LVDS output clock of up to 156 MHz.

Application Field of SN65LVDS301ZQE

The SN65LVDS301ZQE is well suited for use in high-speed serial link applications, such as in networking, storage, and consumer applications that use a real-time transmission control protocol/internet protocol (TCP/IP) interface. This device is also suitable for interfacing with flash-type memories, dual-port SRAMs and other ICs with LVDS interface. This device can be used for low-voltage differential signaling (L-VDS) data transmission in existing and next-generation Ethernet and fiber-optic systems.

Moreover, the SN65LVDS301ZQE can be used in applications such as digital data transport and multimedia (DVB-T, DVB-C, or HSDPA). It offers low power consumption and fast operation, which makes it suitable for applications such as digital subscriber line (DSL) or cable modems, XAUI or SGMII applications, and digital video broadcasting systems. Furthermore, it is also used in automotive applications as digital audio broadcasting (DAB) systems, and in power-over-Ethernet (PoE) systems.

Working Principle of SN65LVDS301ZQE

The SN65LVDS301ZQE is a fully integrated LVDS serializer/deserializer (SerDes). It includes an LVDS transmitting section, an LVDS receiving section, and an internal mux for switching data paths between the transmitter and receiver. The entire serializer/deserializer (SerDes) device is controlled by a selectable clock that is generated from the internal data rate controller (DRC).

The SN65LVDS301ZQE can transmit and receive data at data rates up to 8 Gb/s. It receives data from an 8-bit input data shift register and transmits data to an 8-bit output data shift register. The internal data multiplexer routes the data to the appropriate output, depending on the clock signal. The device also converts the LVDS clock signals to low-voltage single-ended (LVCMOS) signals.

The SN65LVDS301ZQE also has a built-in power saving feature that shutdowns the transmitter section when the device is not in use—reducing the overall power consumption. It also features a built-in voltage regulator that provides power and ground to the device substrate.

The SN65LVDS301ZQE also provides a configurable output enable signal, allowing the device to be used in applications where the output enable pin can be connected to a microprocessor or logic device to enable or disable the output.

Conclusion

The SN65LVDS301ZQE is an integrated serializer/deserializer (SerDes) device that simplifies the design of high-speed serial links. It is well suited for use in high-speed serial link applications, and is suitable for interfacing with flash-type memories, dual-port SRAMs, and other ICs with LVDS interface. The device can transmit and receive data at data rates up to 8 Gb/s, and features a built-in power saving feature, as well as a configurable output enable signal. It is a useful device for Ethernet and fiber-optic systems, as well as for digital data transport and multimedia applications.
