SN65LVDS32NS is an integrated serializer/deserializer (SerDes) from Texas Instruments. It is an example of an interface device, which is capable of transferring data between two components with different data signaling standards. SN65LVDS32NS converts LVDS signals to and from another standard, such as specific standards for physical layer transmissions or full layer protocol standards. Applications for the product vary from consumer audio-video applications to broader industrial applications such as automotive and medical applications. This article will cover the application fields, working principles and technical specifications of the SN65LVDS32NS.

Application Fields and Working Principle

The SN65LVDS32NS is a small 3.3mm by 4.4 mm integrated circuit which supports up to four channels of data that ranges from 6 Mbps to 32 Mbps. The device is a Low Voltage Differential Signaling (LVDS) serializer/deserializer, which is used to transmit digital data between two devices with different data signaling standards. It uses LVDS signaling technology, which is optimized for high-speed data transmission over short or long distances, and allows for faster data rates with lower bit-error rates than regular single-ended voltage-level signaling. The device is mainly used in consumer audio-video applications, to bridge the gap between new and existing standard formats, and in automotive and medical applications.

In applications such as consumer audio-video, the SN65LVDS32NS is most commonly used to manage the data translation between an old and new standard format. For example, the device can manage data transmission from an HDMI output to a DVI input. By using the SN65LVDS32NS, the serial data is converted to LVDS and then transmitted using the new input standard. This provides a bridge between the two standards, resulting in a better quality signal with lower bit errors.

In automotive and medical applications, the SN65LVDS32NS is used to manage data transmission between sensors and signal controllers. For example, in automotive applications, the device is used in applications such as touch screens, infotainment systems, and advanced driver assistance systems (ADAS). The device is also used in medical applications such as patient monitoring, blood pressure monitoring, and cardiovascular monitoring.

Technical Specifications

The SN65LVDS32NS has a data rate of up to 32 Mbps for each channel, with the total data rate up to 128 Mbps. The device has a Differential Output Voltage of 500mV, with a Differential Output Impedance of 200Ω. The SN65LVDS32NS is a low power device, with a typical operating current of 15 mA and a typical standby current of 1.6 mA. The device also has an operating temperature range of -40°C to +85°C and is capable of a maximum Input Reference Voltage of 3.3V.

The SN65LVDS32NS has an integrated 2-bit resolution ADC, which allows data acquisition from external sources, eliminating the need for an external ADC. The device also has adjustable target termination resistor values, which allows for flexible control of measurement targets or automatic adaptation of different conditions. The SN65LVDS32NS also has a built-in autocalibration feature, which enables optimization of the target device’s output impedance for improved stability and noise immunity.

The SN65LVDS32NS is pin compatible with the SN75LV34NS, and is housed in a 6-pin-package. The pin-out is as follows: NC – No Connection; BIN – Serial Data Input; SYN – Serial Data Output; T – Termination pin; REF- Adjustable Input Reference Voltage; VCC – power supply input.
