LVDS terminology explanation and principle application



LVDS - Low Voltage Differential Signaling is a differential input/output system that utilizes terminal resistors (100 Ω) to form a small differential voltage of 350 mV. This differential voltage signal is suitable for high-speed data transmission applications and has better resistance to noise interference in wired data transmission. The small voltage swing can reduce power consumption on the line.
Advantages of LVDS output:
1. Not easily affected by noise interference.
Compared to CMOS/TTL, EMI emissions are lower.
3. Lower voltage fluctuations (usually 350 mv) and lower power consumption compared to PECL output.
Disadvantages of LVDS output:
Compared to PECL, it reduces jitter performance.
