DS15BR401TSQX application field and working principle

The DS15BR401TSQX device is a MIPI based retimer solution, designed for interfacing with MIPI based cameras and displays. It is a type of interface signal buffer, repeater, splitter, used to amplify and redistribute signals to improve signal integrity, distance, and skew over extended lengths. The buffer also operates at high speeds of up to 18 Gb/s and can be used in a variety of applications such as high-speed point-to-point and multi-lane configurations, automotive infotainment systems, and mobile display infrastructure.

The DS15BR401TSQX device is composed of three main components: the clock generation and retiming module, the serializer-deserializer (SERDES) block, and the I/O circuitry. The SERDES block supports the MIPI D-PHY protocol and features data rates from 1.25 to 18 Gb/s depending on the combination of serial and unidirectional terminal connections. The I/O circuitry features eight bidirectional and eight unidirectional pins, which are used for the MIPI data, control, clock, and power signals.

The device also features an embedded jitter attenuation loop and a clock recovery regenerator (CDR) for each pair of input and output paths. The clock generation and retiming block is used to generate the high-frequency reference clock signal and to provide jitter-free clocking performance in the device. The integrated jitter attenuation loop serves to reduce jitter on signals downstream of the device.

The DS15BR401TSQX device also functions as a repeater and signal splitter, providing signal buffering, retiming, and signal routing capabilities between two or more MIPI-compatible devices. The device is able to redistribute signals to adjacent devices and supports multi-pair routing of serial or unidirectional signals for both point-to-point and multi-lane configurations. The device also features a skew compensation engine with up to 1.5ns of adjustable compensation on an eight lane system.

The DS15BR401TSQX is designed for a variety of applications, such as automotive infotainment systems, mobile display infrastructure, and point-to-point and multi-lane configurations. It can also be used in video link applications for the transfer of audio and video data in professional cameras and drones. The device is capable of supporting multiple data channels and can scale the data rate of multiple lanes nero maximum performance.
