M-LVDS Features<br />
M-LVDS Devices from TI<br />
Type 1 Type 2<br />
2.4 V<br />
• TIA/EIA-899 standard<br />
• Driver output current<br />
• 11.3 mA vs. 3.5 mA (LVDS)<br />
• Receiver thresholds<br />
• 50 mV vs. 100 mV (LVDS)<br />
• Driver edge rate control<br />
• 1 ns min allows ease-of-stub design<br />
• Contention provisions<br />
• Driver short circuit limited to 43 mA<br />
• Drivers, receivers and disabled<br />
devices must limit their bus voltage<br />
from 0 to 2.4 V<br />
• Drivers are tested with 32<br />
contending nodes<br />
• TIA/EIA-899 standard compliant<br />
guarantees true multipoint<br />
• Type 1 receivers: 25-mV hysteresis<br />
to prevent oscillation<br />
• Type 2 receivers: internal failsafe<br />
(no external bias network)<br />
• –1-V to 3.4-V common mode<br />
• 3.3-V supply operation<br />
