FIN1047 3.3V LVDS 4-Bit Flow-Through High Speed Differential Driver
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) technol-
ogy. The driver translates LVTTL signal levels to LVDS lev-
els 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 trans-
fer of clock and data.
The FIN1047 can be paired with its companion receiver,
the FIN1048, or any other LVDS receiver.
Features
Greater than 400Mbs data rate
Flow-through pinout simplifies PCB layout
3.3V power supply operation
0.4 ns maximum differential pulse skew
1.7 ns maximum propagation delay
Low power dissipation
Power-Off protection
Meets or exceeds the TIA/EIA-644 LVDS standard
Pin compatible with equivalent RS-422 and LVPECL
devices
16-Lead SOIC and TSSOP packages save space
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
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.
