DS91M040TSQE/NOPB

The DS91M040TSQE/NOPB is a quad M-LVDS Transceiver designed for driving/receiving clock or data signals to from up to four multipoint networks. M-LVDS (multipoint LVDS) is a new family of bus interface devices based on LVDS technology specifically designed for multipoint and multidrop cable and backplane applications. It differs from standard LVDS in providing increased drive current to handle double terminations that are required in multi-point applications. Controlled transition times minimize reflections that are common in multipoint configurations due to unterminated stubs. M-LVDS device also has a very large input common mode voltage range for additional noise margin in heavily loaded and noisy backplane environments. A single DS91M040 channel is a half-duplex transceiver that accepts LVTTL/LVCMOS signals at the driver inputs and converts them to differential M-LVDS signal levels.

• Wide input common mode voltage range allows up to ±1V of GND noise
• Conforms to TIA/EIA-899 M-LVDS standard
• Pin selectable M-LVDS receiver type (1 or 2)
• Controlled transition times (2ns typical) minimize reflections
• Flow-through pin-out simplifies PCB layout
• 8kV ESD on M-LVDS I/O pins protects adjoining components
• Green product and no Sb/Br
