IntroductionThe SN65LV1023ADB is a high performance three-channel LVDS (Low Voltage Differential Signaling) interface IC offering high speed and low power operation. It provides an ideal way to integrate multiple interface modules, such as VGA (Video Graphics Array), SDI (Serial Digital Interface), and HDMI (High-Definition Multimedia Interface). The SN65LV1023ADB offers a programmable I/O delay compensation feature to ensure the data is clocked and aligned correctly. This feature enables the simultaneous connection of multiple LVDS channels with different data rates and provides a delay of up to ±150 ns between the outputs.Application FieldsThe SN65LV1023ADB interface IC is well suited for a wide variety of applications, particularly when cascading numerous data interface modules for multi-channel communications. Its high data rates of up to 3.125 Gbps, combined with its low power consumption and simultaneous support for multiple interfaces, provide an ideal option for real-time, quality-of-service digital video applications. The chip is also features a wide range of digital logic levels (from 3.3 V to 5.0 V) and flexible latency levels, making it a suitable choice for many digital video applications.For example, the SN65LV1023ADB can be used to connect a USB (Universal Serial Bus) or Firewire ports to a computer. It can also be used to connect multiple cameras or monitors to a laptop or a desktop computer. Moreover, it is also used in personal entertainment systems, such as gaming consoles, as well as in professional applications, such as broadcast TVs, medical imaging, and surveillance systems.Working PrincipleThe SN65LV1023ADB interface IC works by providing a low voltage differential transmission over the LVDS link. It is based on a simple yet effective concept in which two lines the \'energized\' line and the \'grounded\' line transmit data. The IC generates an output signal (EOUT) from the three inputs (CIN, IN1, and IN2) and an input clock (CLK). The EOUT signal is then sent to the receivers (inputs to the SN65LV1023ADB IC) and is subsequently converted back to the original logic value by the output buffers. The core circuitry inside the SN65LV1023ADB IC consists of two independent 1-bit serializers and two 1-bit deserializers. The serializers convert the three inputs signals (CIN, IN1, and IN2) and the CLK input into a single EOUT signal. On the other hand, the deserializers convert the EOUT signal back into the original logic signals (CIN, IN1 and IN2). The clock circuit inside the SN65LV1023ADB IC synchronizes the data transmission, thereby reducing the skew between the outputs. The SN65LV1023ADB IC also features an integrated programmable delay line within the clock circuit. This programmable delay line allows the user to adjust the delay between the inputs and the output, thus enabling the LVDS link to support a wide range of data rates. ConclusionThe SN65LV1023ADB is a high performance, low power LVDS interface IC that can be used to connect a variety of data interfaces. Its adjustable delay line and ability to support multiple interfaces allow it to be used in a variety of digital video applications, such as personal entertainment systems, broadcast TVs and medical imaging equipment. The SN65LV1023ADB\'s combination of high data rate and low power consumption make it a suitable choice for real-time, quality-of-service digital video applications.
