Gennum GS9009ACKB Genlinx -tm gs9009a cable driver with four adjustable output Datasheet

GENLINX ™ GS9009A Cable Driver
with Four Adjustable Outputs
DATA SHEET
DESCRIPTION
• two output pairs, adjustable from 0 to 1100mVp-p into
75 Ω loads
The GENLINX™ GS9009A is a bipolar integrated circuit
designed to drive four 75 Ω 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

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.

NOT RECOMMENDED FOR NEW DESIGNS
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

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.
