FIN1026
3.3V LVDS 2-Bit High Speed Differential Receiver
FIN1026 3.3V LVDS 2-Bit High Speed Differential Receiver
General Description
This dual receiver is designed for high speed interconnects
utilizing Low Voltage Differential Signaling (LVDS) technology. The receiver translates LVDS levels, with a typical differential input threshold of 10 0mV, 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 FIN1026 can be paired with its companion dr iver, the
FIN1025, or any other LVDS driver.
Features
■ Greater than 400Mbs data rate
■ Flow-through pinout simpli f ies PCB layout
■ 3.3V power supply operation
■ 0.4ns maximum differential pulse skew
■ 2.5ns maximum propagation delay
■ Low power dissipation
■ Power-Off protection
■ Fail safe protection for ope n-circuit, shorted and termi-
nated non-driven input conditions
■ Meets or exceeds the TIA/EIA-644 LVDS standard
■ 14-Lead TSSOP package saves space
