GS9007ACKA

Overview

The GS9007ACKA is a quad output serial digital video cable driver manufactured by Gennum. Designed for SMPTE 259M compliance, it drives four 75Ω coaxial cables with adjustable output amplitudes ranging from 50mV to 1000mV. The device operates at data rates from 143Mb/s to 540Mb/s and beyond, featuring nominal 500ps rise/fall times and precise ±7.5% output amplitude matching. It includes 75Ω on-chip input termination resistors and an input hysteresis feature. The component supports operation down to an 80mV input amplitude and provides superior output isolation.

Feature Summary

• Four isolated outputs configured as two complimentary pairs for driving coaxial transmission lines
• Integrated 75Ω on-chip input termination resistors to simplify circuit design
• Bus Through expansion port capability to support fan-out requirements

Applications

• Serial digital video coaxial transmission interfaces operating between 143 and 540Mb/s
• General purpose cable driving applications utilizing coaxial cable or UTP
• 4fsc, 4:2:2, and 4:4:4:4 serial digital video signal distribution

Procurement Notes

Verify the specific suffix ACKA against official Gennum documentation to confirm package type and temperature range. Confirm current availability status as legacy components may have limited supply chains. Ensure compatibility with existing system voltage levels and interface requirements before procurement.

Selection Notes

Select this component when SMPTE 259M compliance is required for multi-channel video distribution. Consider the adjustable amplitude range for varying cable lengths and load conditions. Evaluate the power reduction benefits compared to previous generation drivers if upgrading existing designs.

Part Context

The GS9007ACKA belongs to the Gennum GENLINX family of serial digital video processors. It serves as a cable driver solution for professional broadcast and video infrastructure. The device addresses the need for high-speed, multi-channel signal integrity in standard definition and high definition video environments.

Replacement Considerations

The datasheet notes a 40% system power reduction over the GS9007 model. Verify pinout and electrical specifications against the GS9007 if considering a direct upgrade within the same product line.
