GS2978 HD-LINX® III Multi-Rate Dual Slew-Rate Cable Driver
Features
• SMPTE 424M, SMPTE 292M, SMPTE 344M and SMPTE
259M compliant
• Dual coaxial cable driving outputs with selectable
slew rate
• 50Ω differential PECL input
• Pb-free and RoHS compliant
• Seamless interface to other HD-LINX® III family
products
• Single 3.3V power supply operation
• Operating temperature range: 0°C to 70°C
Applications
• SMPTE 424M, SMPTE 292M, SMPTE 344M and SMPTE
259M Coaxial Cable Serial Digital Interfaces.
Description
The GS2978 is a high-speed BiCMOS integrated circuit
designed to drive one or two 75Ω co-axial cables.
The GS2978 may drive data rates up to 2.97Gb/s and
provides two selectable slew rates in order to achieve
compliance to SMPTE 424M, SMPTE 259M, SMPTE 344M
and SMPTE 292M.
The GS2978 accepts a LVPECL level differential input that
may be AC coupled. External biasing resistors at the inputs
are not required.
Power consumption is typically 168mW using a 3.3V
power supply. The GS2978 is Pb-free, and the
encapsulation compound does not contain halogenated
flame retardant.
This component and all homogeneous subcomponents are
RoHS compliant.
