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) technol-
ogy. The driver translates LVTTL signal levels to LVDS lev-
els 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 trans-
fer of clock or data.
The FIN1001 can be paired with its companion receiver,
the FIN1002, or with any other LVDS receiver.
Features
I Greater than 600Mbs data rate
I 3.3V power supply operation
I 0.5ns maximum differential pulse skew
I 1.5ns maximum propagation delay
I Low power dissipation
I Power-Off protection
I Meets or exceeds the TIA/EIA-644 LVDS standard
I Flow-through pinout simplifies PCB layout
I 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.

Note 3: All typical values are at TA = 25°C and with VCC = 3.3V.
Note 4: tSK(PP) is the magnitude of the difference in propagation delay times between any specified terminals of two devices switching in the same direction
(either LOW-to-HIGH or HIGH-to-LOW) when both devices operate with the same supply voltage, same temperature, and have identical test circuits.
