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, 260m at 1.485Gb/s and 500m at 270Mb/s. In cable driver mode, the dual slew rate capability provides compatibility to SMPTE ST 424, SMPTE ST 292 and SMPTE ST 259 interfaces. GS3490 Block Diagram CD EQ SDI/SDO CD DDO DDI DDI DDO |
