ETC GS9007

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

• 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.
