Semtech GS3490

Configurable Multi-rate 3G Cable Driver and Adaptive Equalizer

Add to Watch List

 The GS3490 features integrated adaptive cable equalizerand cable driver functionality. The GS3490 can be field-configured as a SMPTE compliant cable equalizer or a SMPTE compliant cable driver.

The GS3490 is optimized for applications with limited I/O space. With its configurable EQ and Cable driver functionality, the GS3490 can be utilized as a single-device solution in applications where the interface connector can be configured as either an input or output.

The GS3490's cable equalizer is optimized for operation at 2.97Gb/s, 1.485Gb/s and 270Mb/s while providing typical cable reach of 140m at 2.97Gb/s, 250m at 1.485Gb/s and 550m at 270Mb/s.

In cable driver mode, the dual slew rate capability provides compatibility to SMPTE ST 259, SMPTE ST 292 and SMPTE ST 424 interfaces.
