GENLINX ™ GS9009A Cable Driver with Four Adjustable Outputs DATA SHEET DESCRIPTION • two output pairs, adjustable from 0 to 1100mVp-p into 75 : loads The GENLINX™ GS9009A is a bipolar integrated circuit designed to drive four 75 : co-axial cables at data rates exceeding 400Mb/s. It directly interfaces with other GENLINX™ devices and can also be used as a general purpose high speed cable driver. • nominal 600 ps rise and fall times • accepts SMPTE and standard ECL input levels • operates from a single +5 or -5 volt supply • 250 mW power dissipation • interfaces with GENLINX™ GS9002, GS9004A, GS9005A and GS9015A • Pb-free and Green APPLICATIONS • SMPTE 259M Serial Digital Systems (4:2:2 & 4ƒsc) • Other Serial Digital Video Interfaces — 360Mb/s • General purpose high speed driver applications PIN CONNECTIONS NC 1 14 NC NC 2 13 NC OUTPUT 1 3 OUTPUT 1 4 12 VCC 11 INPUT GS9009A OUTPUT 2 5 10 INPUT OUTPUT 2 6 9 VEE VSET 7 8 VREF Correctly terminated output signal levels are adjustable from as low as 0mV to as high as 1100mV with little change in other performance parameters. Performance is guaranteed for output levels between 600 mV and 1000 mV. The gain of the output stages is varied by adjusting the VSET voltage with respect to an internal bandgap reference voltage VREF. Pinout is compatible with the GS9007A by interchanging pins 3,4,5,6,9,10,11,12 on the GS9009A with pins 1,2,3,4,5,6,7,8 on the GS9007A. In this way, a layout can be made for either device depending on whether adjustability is desired or not. The GS9009A is packaged in a 14 pin SOIC, and operates from a single +5 or -5 volt supply consuming typically only 250mW of power.

Even though the inputs are AC coupled, static protection diodes at each input restrict the DC differential so that if the driving source uses the opposite polarity power supply, external DC blocking capacitors must be used. • on-chip DC restoration for low jitter GS9009A KEY FEATURES ABSOLUTE MAXIMUM RATINGS PARAMETER VALUE Supply Voltage (VS) 5.5V Input Voltage Range (any input) VS -0.5V Power Dissipation 300mW GS9009A 0°C d TA d 70°C Operating Temperature Range -65°C d TS d 150°C Storage Temperature Range Lead Temperature (soldering, 10 sec) 260°C GS9009A CABLE DRIVER — DC ELECTRICAL CHARACTERISTICS Conditions: VS = 5V, TA = 0°C to 70°C, RL= 150 : to GND and 144 : AC coupled unless otherwise shown SYMBOL CONDITIONS MIN TYP MAX UNITS 4.5 5.0 5.5 volts - 250 290 mW - 105 110 mA Supply Voltage VS Power Consumption PD Supply Current ,S1 4 x150: Loads DC 1% Accuracy, TA= 25°C VSET = (0.667) VREF Supply Current ,S2 DC No Loads, TA= 25°C - 16 20 mA 10 k: to ground - 1.2 - volts Reference Voltage VREF NOTES GS9009A CABLE DRIVER — AC ELECTRICAL CHARACTERISTICS Conditions: VS = 5V, TA = 0°C to 70°C, RL= 150 : to GND and 144 : AC coupled unless otherwise shown PARAMETER MIN TYP MAX UNITS VIN 700 800 1000 mVp-p Input Signal Rise/Fall Times tR,tF - - 750 ps Output Amplitudes across 75 : Load (See Note 1) VOUT VSET = (0.5) VREF 540 600 660 mVp-p Note 1 & 2 VSET = (0.667) VREF 720 800 880 mVp-p Note 1 & 2 VSET = (0.833) VREF 900 1000 1100 mVp-p Note 1 & 2 VSET = (0.5) VREF - 25 100 ppm/°C VSET = (0.667) VREF - -12 80 ppm/°C VSET = (0.833) VREF - -45 80 ppm/°C VSET = (0.5) VREF 400 630 800 ps VSET = (0.667) VREF 400 575 800 ps VSET = (0.833) VREF 400 530 800 ps tR= tF = 600 ps - 0 - % at 270Mb/s - - ±25 ps - 1 - ns Input Signal Amplitude Output Amplitude Temperature Coefficient (See Note 2) Output Rise/Fall Times (20% to 80%) SYMBOL TC tR,tF Output Overshoot Jitter tJ Propagation Delay tP CONDITIONS NOTES See Figure 3 1. VOUT is measured across a correctly terminated load, back matched to the device. The peak to peak voltage of the device itself is 2 x VOUT. 2. VOUT is proportional to VSET and VSET may be an external low impedance, high stability supply. In this case the amplitude temperature coefficient will not be guaranteed. 2 of 4 GENNUM CORPORATION 29782 - 1 NOT RECOMMENDED FOR NEW DESIGNS PARAMETER INPUT/OUTPUT CIRCUITS VCC VCC VCC VCC 400 400 VREF1 0.5p GS9009A SERIAL INPUTS VOUT 400 VREF1 + VREF2 VCC NOT RECOMMENDED FOR NEW DESIGNS Figure 1 VOUT Input Circuit (Pins 11 and 12) Figure 2 Output Circuit (Pins 3, 4 and 5, 6) 0.1 +5V 1.8p OUTPUT LEVEL ADJUST 1.0 68 OUTPUT -2 (75Ω) 10k 1.8p 8 7 9 6 68 OUTPUT -2 (75Ω) 1.0 INPUT SIGNAL 10 INPUT SIGNAL 11 5 68 1.0 GS9009A OUTPUT -1 (75Ω) 4 1.0 12 1.8p 3 13 2 14 1 68 + 1 0.1 10 2 3 OUTPUT -1 (75Ω) 4 1.8p All resistors in ohms, all capacitors in microfarads unless otherwise stated.
