Revised February 2002 FIN1002 LVDS 1-Bit High Speed Differential Receiver General Description Features This single 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 100 mV, 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 or data. ■ Greater than 400Mbs data rate The FIN1002 can be paired with its companion driver, the FIN1001, or with any other LVDS driver. ■ Fail safe protection for open-circuit and non-driven, shorted or terminated conditions ■ 3.3V power supply operation ■ 0.4ns maximum pulse skew ■ 2.5ns maximum propagation delay ■ Bus pin ESD (HBM) protection exceeds 10kV ■ Power-Off over voltage tolerant input and output ■ High impedance output at VCC < 1.5V ■ Meets or exceeds the TIA/EIA-644 LVDS standard ■ 5-Lead SOT23 package saves space Ordering Code: Order Number Package Number Package Description FIN1002M5 MA05B 5-Lead SOT23, JEDEC MO-178, 1.6mm [250 Units on Tape and Reel] FIN1002M5X MA05B 5-Lead SOT23, JEDEC MO-178, 1.6mm [3000 Units on Tape and Reel] Pin Descriptions Pin Name Connection Diagram Description ROUT LVTTL Data Output RIN+ Non-inverting Driver Input RIN− Inverting Driver Input VCC Power Supply GND Pin Assignment for SOT package Ground NC No Connect Top View Function Table Input Outputs RIN+ RIN− L H L H L H ROUT Fail Safe Condition H H = HIGH Logic Level L = LOW Logic Level Fail Safe = Open, Shorted, Terminated © 2002 Fairchild Semiconductor Corporation DS500730 www.fairchildsemi.com FIN1002 LVDS 1-Bit High Speed Differential Receiver February 2002 FIN1002 Absolute Maximum Ratings(Note 1) Supply Voltage (VCC) −0.5V to +4.6V DC Input Voltage (RIN+, RIN−) −0.5V to +4.6V DC Output Voltage (DOUT) Recommended Operating Conditions Supply Voltage (VCC) −0.5V to +6V DC Output Current (IO) 16 mA Storage Temperature Range (TSTG) Voltage (|VID|) 100mV to VCC 150°C Common-mode Input 260°C Operating Temperature (TA) Lead Temperature (TL) (Soldering, 10 seconds) 0 to VCC Magnitude of Differential −65°C to +150°C Max Junction Temperature (TJ) 3.0V to 3.6V Input Voltage (VIN) (0V + |VID| /2) to (2.4 − |VID|/2) Voltage (VIC) −40°C to +85°C ESD (Human Body Model) All Pins 8kV LVDS pins to GND 10kV ESD (Machine Model) 400V 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.
