FIN1027 • FIN1027A 3.3V LVDS 2-Bit High Speed Differential Driver
FIN1027 • FIN1027A
3.3V LVDS 2-Bit High Speed Differential Driver
General Description
This dual 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 FIN1027 or FIN1027A can be paired with its compan-ion receiver, the FIN1028, or with any other LVDS receiver.
Features
s Greater than 600Mbs data rate s 3.3V power supply operation
s 0.5ns maximum differential pul skew s 1.5ns maximum propagation delay s Low power dissipation s Power-Off protection
s Meets or exceeds the TIA/EIA-644 LVDS standard s Flow-through pinout simplifies PCB layout s 8-Lead SOIC, US8, and 8-terminal MLP packages save space

Absolute Maximum Ratings (Note 1)
Recommended Operating Conditions
Note 1: The “Absolute Maximum Ratings ”: are tho 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 T A = 25°C and with V CC = 3.3V.
Note 4: t SK(LH), t SK(HL) is the skew between specified outputs of a single device when the outputs have identical loads and are switching in the same direc-tion.
Note 5: t SK(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.
