A SN75DP128RTQR is a 3xLVDS-miocro-PISO interface IC for applications such as digital video and high speed communications. It features dual lanes of Duplex LVDS (Low Voltage Differential Signaling) communications, high speeds and low power dissipation, making it an attractive interface IC in a variety of applications.

The SN75DP128RTQR has two primary functions: one is to provide an LVDS data interface and the other is to offer more parallelism. LVDS is a differential signaling protocol which is used in most high speed data communications and digital video applications due to its advantages in terms of noise immunity, power savings, and higher data rates. The parallelism function of the SN75DP128RTQR allows multiple LVDS data channels to be combined into a single serial stream.

The SN75DP128RTQR supports up to 8-bit LVDS parallel data inputs and 8-bit LVDS parallel data outputs. It also supports single ended (SE) or differential (DIFF) LVDS data inputs across four differential pairs. The RTQR is able to dynamically switch between single-ended (SE) and differential (DIFF) mode. In addition, the SN75DP128RTQR operates from a single +3V power supply, consuming only 170 mW.

Working Principle

The SN75DP128RTQR is a fast LVDS interface IC that enables high speed data communication and digital video applications. The device features a 14-bit differential input interface to accept a single-ended or a differential LVDS signal, a 14/_10-bit conversion, high speed data algorithm, dual data rate operation and a byte ALIGN feature. The RTQR also supports the generation of two LVDS clocks and programmable output frequency.

The SN75DP128RTQR uses a dual differential input voltage range of 0.2V to 2V and a dual differential output voltage range of 500mV to 2V. At a data rate of 1 Gbps, the SN75DP128RTQR has a power dissipation of only 170 mW. The device offers a range of features such as clock skew compensation, signal pre-emphasis, programmable clock jitter, wide edge testing, wide input signal pre-process and programmable output frequency. The chip also supports LVDS data rates up to 12 Mbps.

Applications

The SN75DP128RTQR is ideal for applications such as digital video, high-speed communications, baseband signal processing, point-to-point data transmission, serial data transfer, signal arbitration, power line communications, serial/parallel conversion and LVDS signal conditioning. It can also be used for gigabit Ethernet, FireWire, SATA, USB and video transmission standards such as HDMI and DisplayPort.

The SN75DP128RTQR supports wide edge testing and power line communications, allowing the device to operate in noisy environments and to avoid interference from other devices. The chip also has a wide device temperature range, allowing it to be used in a wider range of applications.

In addition, the SN75DP128RTQR is suitable for a variety of commercial and industrial applications, such as automotive, industrial, medical and consumer. It can be used in systems such as HDTV, industrial controllers, advanced driver assistance systems (ADAS) and application servers. The chip can also be used in applications involving digital video and audio processing, multi-channel DAC/ADC, and 4K Ultra HD video.
