FIN1001 3.3V LVDS 1-Bit High Speed Differential Driver
December 2001 Revised August 2004
FIN1001 3.3V LVDS 1-Bit High Speed Differential Driver
General Description
This single driver is designed for high speed interconnects utilizing Low Voltage Differential Signaling (LVDS) technology. The driver translates LVTTL signal levels to LVDS levels with a typical differential output swing of 350 mV which provides low EMI at ultra low power dissipation even at high frequencies. This device is ideal for high speed transfer of clock or data. The FIN1001 can be paired with its companion receiver, the FIN1002, or with any other LVDS receiver.
Features
s Greater than 600Mbs data rate s 3.3V power supply operation s 0.5ns maximum differential pulse skew s 1.5ns maximum propagation delay s Low power dissipation s Power-Off protection s Meets or exceeds the TIA/EIA-644 LVDS standard s Flow-through pinout simplifies PCB layout s 5-Lead SOT23 package saves space

Note 1: The "Absolute Maximum Ratings": are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature and output/input loading variables. Fairchild does not recommend operation of circuits outside databook specification.
