Revised April 2002 FIN1017 3.3V LVDS 1-Bit High Speed Differential Driver General Description Features This single driver is designed for high speed interconnects utilizing Low Voltage Differential Signaling (LVDS) technology. The driver translates LVTTL signal levels to LVDS levels 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 transfer of clock or data. ■ Greater than 600Mbs data rate The FIN1017 can be paired with its companion receiver, the FIN1018, or with any other LVDS receiver. ■ Meets or exceeds the TIA/EIA-644 LVDS standard ■ 3.3V power supply operation ■ 0.5ns maximum differential pulse skew ■ 1.5ns maximum propagation delay ■ Low power dissipation ■ Power-Off protection ■ Flow-through pinout simplifies PCB layout ■ 8-Lead SOIC and US8 packages save space Ordering Code: Order Number Package Number Package Description FIN1017M M08A 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow [TUBE] FIN1017MX M08A 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow [TAPE and REEL] FIN1017K8X MAB08A 8-Lead US8, JEDEC MO-187, Variation CA 3.1mm Wide [TAPE and REEL] Connection Diagrams 8-Lead SOIC Pin Assignment for US-8 Package Note: Ground pins 4 and 5 for optimum operation.
