FIN1048 3.3V LVDS 4-Bit Flow-Through High Speed Differential Receiver
September 2001 Revised August 2003
FIN1048 3.3V LVDS 4-Bit Flow-Through High Speed Differential Receiver
General Description
This quad receiver is designed for high speed interconnect utilizing Low Voltage Differential Signaling (LVDS) technology. The receiver translates LVDS levels, with a typical differential input threshold of 100mV, to LVTTL signal levels. LVDS 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 FIN1048 can be paired with its companion driver, the FIN1047, or any other LVDS driver.
Features
s Greater than 400Mbs data rate s Flow-through pinout simplifies PCB layout s 3.3V power supply operation s 0.4ns maximum differential pulse skew s 2.5ns maximum propagation delay s Low power dissipation s Power-Off protection s Fail safe protection for open-circuit, shorted and terminated conditions 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

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.
