APPLICATIONS
•4ƒ
SC, 4:2:2 and 360Mb/s Serial Digital Interfaces.
The GENLINX ™ GS9007A is a bipolar intergrated circuit
designed to drive four 75Ω co-axial cables with SMPTE
level serial digital video signals at data rates up to 360Mb/s.
It directly interfaces with other GENLINX ™ devices and
can also be used as a general purpose high speed cable
driver.
The differential inputs are AC-coupled and internally
DC-restored wich 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.
The GS9007A is packaged in an 8 pin SOIC, and operates
from a single +5 or -5 volt supply consuming typically only
250mW of power.
