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 GS2964 is a cost optimized short reach equalizer that still supports 100m at 3Gbps. The GS2964 is a high-speed BiCMOS integrated circuit designed to equalize and restore signals received over 75ohm coaxial cable.

本器件专用于支持 SMPTE 424M、SMPTE292M 和 SMPTE 259M，并针对 270Mbps、1.485Gbps 和 2.97Gbps 的性能进行了优化。

The GS2964 features DC restoration to compensate for the DC content of SMPTE pathological test patterns.

The Carrier Detect output pin (CD) indicates whether a valid input signal has been detected. It can be connected directly to the MUTE pin to mute the output on loss of carrier. A voltage programmable threshold, which can be changed via the SQ_ADJ pin, forces CD high when the input signal amplitude falls below the threshold. This allows the GS2964 to distinguish between low-amplitude SDI signals and noise at the input of the device.

当旁路引脚为高电平时，均衡和直流恢复级将断开。在旁路模式下不发生均衡。

The differential outputs can be DC-coupled to Gennum® 3.3V cable drivers and reclockers and to other industry-standard 3.3V CML logic.

The GS2964 is footprint and drop-in compatible with existing GS2974 designs, with no additional application changes required.

本器件采用 16 引脚、4mm x 4mm QFN 封装。

Power consumption of the GS2964 is typically 215mW.

The GS2964 is Pb-free, and the encapsulation compound does not contain halogenated flame retardant.

This component and all homogeneous subcomponents are RoHS compliant.
