GENLINX™ GS9007 Quad Serial Digital Cable Driver DATA SHEET FEATURES DEVICE DESCRIPTION • two output pairs (four outputs total) meeting SMPTE 259M The GENLINX ™ GS9007 is a bipolar integrated circuit designed to drive four 75 Ω co-axial cables with SMPTE level serial digital video signals at data rates exceeding 400 Mb/s. It directly interfaces with other GENLINX ™ devices and can also be used as a general purpose high speed cable driver. • nominal 550 ps rise and fall times • accepts SMPTE and standard ECL input levels D E D S N E GN M SI M E O D C E R EW T N O N OR F • operates from a single +5 or -5 volt supply The differential inputs are AC-coupled and internally DCrestored which allows correct passage of pathological check codes associated with the serial digital standards. 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 • 250 mW power dissipation • interfaces with GENLINX ™ GS9002, GS9004A, GS9005A and GS9015A PIN CONNECTIONS The GS9007 is packaged in an 8 pin SOIC, and operates from a single +5 or -5 volt supply consuming typically only 250 mW of power.
