Revised September 2002 FIN1101 LVDS Single Port High Speed Repeater General Description Features This single port repeater is designed for high speed interconnects utilizing Low Voltage Differential Signaling (LVDS) technology. It accepts and outputs LVDS levels with a typical differential output swing of 330 mV which provides low EMI at ultra low power dissipation even at high frequencies. It can directly accept multiple differential I/O including: LVPECL, HSTL, and SSTL-2 for translating directly to LVDS. Up to 1.6 Gb/s full differential path 3.5 ps max random jitter and 135 ps max deterministic jitter 3.3V power supply operation Wide rail-to-rail common mode range Ultra low power consumption LVDS receiver inputs accept LVPECL, HSTL, and SSTL-2 directly Power off protection 7 kV HBM ESD protection (all pins) Meets or exceed the TA/EIA-644-A LVDS standard Packaged in 8-pin SOIC and US8 Open circuit fail safe protection Ordering Code: Order Number Package Number Package Description FIN1101M M08A 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow [TUBE] FIN1101MX M08A 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow [TAPE and REEL] FIN1101K8X MAB08A 8-Lead US8, JEDEC MO-187, Variation CA 3.1mm Wide [TAPE and REEL] Connection Diagrams Pin Descriptions Pin Name SOIC Package US8 Package Description RIN+ Non-Inverting LVDS Inputs RIN- Inverting LVDS Inputs DOUT+ Non-Inverting Driver Outputs DOUT- Inverting Driver Outputs EN Driver Enable Pin VCC Power Supply GND Ground Function Table Inputs Functional Diagram RIN+ RIN- DOUT+ H H L H L H L H L H H L H = HIGH Logic Level X = Don't Care (c) 2002 Fairchild Semiconductor Corporation DS500654 Outputs EN Fail Safe Case X X DOUT- H L Z Z L = LOW Logic Level Z = High Impedance www.fairchildsemi.com FIN1101 LVDS Single Port High Speed Repeater January 2002 FIN1101 Absolute Maximum Ratings(Note 1) Supply Voltage (VCC) -0.5V to +4.6V Recommended Operating Conditions LVDS DC Input Voltage (VIN) -0.5V to +4.6V -0.5V to +4.6V Supply Voltage (VCC) LVDS DC Output Voltage (VOUT) Driver Short Circuit Current (IOSD) Storage Temperature Range (TSTG) Continuous 10 mA Magnitude of Input -65C to +150C Differential Voltage (|VID|) 150C Max Junction Temperature (TJ) 260C ESD (Human Body Model) 7000V ESD (Machine Model) 100 mV to VCC Common Mode Input Voltage Lead Temperature (TL) (Soldering, 10 seconds) 3.0V to 3.6V -40C to +85C Operating Temperature (TA) (0V + |VID|/2) to (VCC - |VID|/2) (VIC) 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. 300V DC Electrical Characteristics Over supply voltage and operating temperature ranges, unless otherwise specified Symbol Min Typ Max Parameter Test Conditions VTH Differential Input Threshold HIGH See Figure 1; VIC = +0.05V, +1.2V, or (VCC - 0.05V) VTL Differential Input Threshold LOW See Figure 1; VIC = +0.05V, +1.2V, or (VCC - 0.05V) VIH Input High Voltage (EN) 2.0 VCC V VIL Input Low Voltage (EN) GND 0.8 V VOD Output Differential Voltage VOD VOD Magnitude Change from RL = 100 , Driver Enabled, Differential LOW-to-HIGH See Figure 2 VOS Offset Voltage VOS Offset Magnitude Change from (Note 2) 100 -100 250 1.125 IIN Short Circuit Output Current Input Current (EN, DINX+, DINX-) mV mV 330 1.23 Differential LOW-to-HIGH IOS Units 450 mV 25 mV 1.375 V 25 mV DOUT+ = 0V & DOUT- = 0V, Driver Enabled -3.4 -6 mA VOD = 0V, Driver Enabled 3.4 6 mA 20 A VIN = 0V to VCC, Other Input = VCC or 0V (for Differential Inputs) IOFF Power-Off Input or Output Current VCC = 0V, VIN or VOUT = 0V to 3.6V 20 A ICCZ Disabled Power Supply Current Drivers Disabled 3.2 5.5 mA ICC Power Supply Current Drivers Enabled, Any Valid Input Condition 9.3 13.5 mA IOZ Disabled Output Leakage Current Driver Disabled, DOUT+ = 0V to 3.6V or 20 A VCC- (|VID|/2) V DOUT- = 0V to 3.6V VIC CIN COUT Common Mode Voltage Range |VID| = 100 mV to VCC 0V + |VID|/2 Input Capacitance Output Capacitance 2.2 Data Input 2.0 2.6 Note 2: All typical values are at TA = 25C and with VCC = 3.3V. www.fairchildsemi.com EN Input 2 pF pF FIN1101 AC Electrical Characteristics Over supply voltage and operating temperature ranges, unless otherwise specified Symbol tPLHD Parameter Test Conditions Differential Propagation Delay LOW-to-HIGH tPHLD Differential Propagation Delay RL = 100 , CL = 5 pF, HIGH-to-LOW VID = 200 mV to 450 mV, Min Typ Max (Note 3) Units 0.75 1.1 1.75 ns 0.75 1.1 1.75 ns tTLHD Differential Output Rise Time (20% to 80%) VIC = |V ID|/2 to (VCC- (VID/2), 0.29 0.40 0.58 ns tTHLD Differential Output Fall Time (80% to 20%) Duty Cycle = 50%, 0.29 0.40 0.58 ns tSK(P) Pulse Skew |tPLH - tPHL| See Figure 3 and Figure 4 0.01 0.2 ns tSK(PP) Part-to-Part Skew (Note 4) fMAX Maximum Frequency (Note 5)(Note 6) tPZHD Differential Output Enable Time from Z to HIGH 2.1 5 tPZLD Differential Output Enable Time from Z to LOW RL = 100 , CL = 5 pF, 2.3 5 ns tPHZD Differential Output Disable Time from HIGH to Z See Figure 2 and Figure 3 1.5 5 ns tPLZD Differential Output Disable Time from LOW to Z 1.8 5 ns tDJ LVDS Data Jitter, 85 135 ps 2.1 3.5 ps tRJ 0.5 400 VID = 300 mV, PRBS = 223 - 1, Deterministic VIC = 1.2V at 800 Mbps LVDS Clock Jitter, Random VID = 300 mV (RMS) VIC = 1.2 V at 400 MHz 800 ns MHz ns Note 3: All typical values are at TA = 25C and with VCC = 3.3V, VID = 300mV, VIC = 1.2V unless otherwise specified. Note 4: tSK(PP) is the magnitude of the difference in differential propagation delay times between identical channels 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. Note 5: Passing criteria for maximum frequency is the output VOD > 200 mV and the duty cycle is 45% to 55% with all channels switching. Note 6: Output loading is transmission line environment only; CL is < 1 pF of stray test fixture capacitance. FIGURE 1.
