Low Voltage Differential Signal (LVDS) connector, also known as RS-644 bus interface. The core of this technology is to use extremely low voltage swing to transmit data at a high speed, which has the characteristics of low power consumption, low bit error rate, low crosstalk and low radiation. The transmission medium can be a copper PCB connection or a balanced cable. LVDS has been more and more widely used in systems that require high signal integrity, low jitter and common mode. TXGA product center provides [lvds connector] in stock, place an order immediately and ship on the same day.
Application mode
1. One-way point-to-point
This is a typical application mode of the lvds connector. Each point-to-point differential pair is composed of a driver, an interconnector and a receiver. The driver and receiver mainly complete the conversion between TTL signal and LVDS signal. Interconnects include cables, differential wire pairs on the PCB, and matching resistors. The unidirectional point-to-point application mode is an ideal interface for communication between chips, plug-ins, and racks.
2. Two-way point-to-point
Two-way half-duplex communication can be realized through a pair of twisted pairs. It can be composed of standard LVDS drivers and receivers. But a better way is to use a bus LVDS driver, namely BlVDS, which is designed for both ends of the bus to be connected to the load.
3. Multi-branch form
That is, one driver is connected to multiple receivers. When there is the same data to be transmitted to multiple loads, this application form can be used.
4. Multi-point structure
At this time, the multipoint bus supports multiple drivers, and BLVDS drivers can also be used. It can provide two-way half-duplex communication, but at any one time, only one drive can work. Therefore, the priority of the transmission and the arbitration protocol of the bus need to be selected according to different applications, and different software protocols and hardware schemes.
