This product has reached its End of Life. Its data sheet is for reference only.
Please use GS2994, GS3440 and GS3140 for new designs.
The GS2974A is a high-speed BiCMOS integrated circuit designed to equalize and restore signals received over 75Ω co-axial cable.
The GS2974A is designed to support SMPTE 424M, SMPTE 292M and SMPTE 259M, and is optimized for performance at 1.485Gb/s and 2.97Gb/s.
The GS2974A features DC restoration to compensate for the DC content of SMPTE pathological test patterns.
A voltage programmable mute threshold (MCLADJ), applicable for HD and SD mode (refer to Section 5.2), is included to allow muting of the GS2974A output when an approximate selected cable length is reached for SMPTE 259M signals. This feature allows the GS2974A to distinguish between low amplitude SD-SDI signals and noise at the input of the device. The serial digital outputs of the GS2974A may be forced to a mute state by applying a voltage to the MUTE pin.
Power consumption is typically 215mW using a 3.3V power supply. The GS2974A is lead-free, and the encapsulation compound does not contain halogenated flame retardant.
This component and all homogeneous subcomponents are RoHS compliant.

The Challenge of Drain Grate Maintenance
In urban and industrial water management, drain grates play a crucial role in preventing debris from clogging sewage systems, retention basins and hydropower plants. These grates filter out foliage, branches and other obstructions, ensuring the smooth flow of water. However, over time, debris accumulation can lead to blockages, increasing the risk of flooding and requiring frequent manual inspections.
