LVDS cables are widely used in computers, medical devices, laptops, HD cameras, televisions, smartphones, industrial electronics, and consumer devices and are characterized by high-speed serial transmission.
Cable usage: miniature coaxial cable, excellent coaxial cable, MCX cable, multi-pole shielded cable, single flexible cable, Teflon cable
Connectors: JAE, HIROSE, MOLEX, JST, I-PEX, etc., depending on board end requirements, with 0.3/0.4/0.5/0.6/0.8/1.0/1.25/1.5mm pitch
LVDS cable processing requires high reliability, and the connection line can ensure signal quality through impedance matching and minimum crosstalk. The signal connection lines are twisted to achieve a matching resistance of 100Ω to reduce signal attenuation and shielding to comply with EMC regulations, reducing electromagnetic noise.
LVDS (LOW-VOLTAGE DIFFERENTIAL SIGNALING) is a low-power, low-crosstalk, and low-radiation differential signal technology that can transmit up to 155mbps or more. The core of LVDS technology is the high-speed differential transmission of data with shallow voltage swing, allowing point-to-point or point-to-multipoint connections.
LVDS technology features
1. High speed: LVDS logic states can change states very quickly because the voltage change between states is only 350 MV, thus achieving high efficiency
2. Low power consumption: LVDS supply current remains flat as the operating frequency increases, while CMO and GTL technologies show an exponential increase in supply current with increasing frequency, thanks to the use of constant-current line drivers, which also tolerate short-circuiting or grounding of the transmission line without thermal problems, and LVDS lowers the total power consumption of the circuit by depressing the terminal resistance drop
3. Good noise characteristics: LVDS generates low EMI due to low voltage swing, low edge rate, odd differential signals, and the IS spikes of the constant current driver produce only very low radiation by reducing voltage swing and current energy in the lowest EMI from the current.
4. Fail-safe feature ensures reliability, constant-current drivers do not cause any harm so that LVDS drivers can be plugged in and out with power, and another feature is the receiver fail-safe feature
Cost savings: LVDS technology can be implemented in an economic CMO process and does not require harsh cable connector and PCB materials to achieve high performance at a low cost
High Integration Capability: Because high-speed LVDS analog circuits can be implemented in a standard CMO process, it is very advantageous to integrate complex digital functions.
