FIN1047 3.3V LVDS 4-Bit Flow-Through High Speed Differential Driver
General Description
This quad 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 350mV which provides low EMI at ultra low power dissipation even at high frequencies. This device is ideal for high speed transfer of clock and data. The FIN1047 can be paired with its companion receiver, the FIN1048, or any other LVDS receiver.

Features
s Greater than 400Mbs data rate s Flow-through pinout simplifies PCB layout s 3.3V power supply operation s 0.4 ns maximum differential pulse skew s 1.7 ns maximum propagation delay s Low power dissipation s Power-Off protection s Meets or exceeds the TIA/EIA-644 LVDS standard s Pin compatible with equivalent RS-422 and LVPECL devices s 16-Lead SOIC and TSSOP packages save space
