3.3V LVDS High Speed Differential Driver/Receiver
(Preliminary)
General Description
Features
This driver and receiver pair are designed for high speed
interconnects utilizing Low Voltage Differential Signaling
(LVDS) technology. The driver translates LVTTL signals to
LVDS levels with a typical differential output swing of
350mV and the receiver translates LVDS signals, with a
typical differential input threshold of 100mV, into LVTTL
levels. LVDS technology provides low EMI at ultra low
power dissipation even at high frequencies. This device is
ideal for high speed clock or data transfer.
■ Greater than 400Mbs data rate
■ 3.3V power supply operation
■ 0.5ns maximum differential pulse skew
■ 2.5ns maximum propagation delay
■ Low power dissipation
■ Power OFF protection
■ 100mV receiver input sensitivity
■ Fail safe protection open-circuit, shorted and terminated
conditions
■ Meets or exceeds the TIA/EIA-644 LVDS standard
■ Flow-through pinout simplifies PCB layout
■ 14-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.
