The device can be configured either in the input mode as an equalizer to receive data over coaxial cable or in the output mode as a cable driver to transmit data over coaxial cable. The same I/O pin is used both for the input and the output functions of the device, allowing the system designer the flexibility to use a BNC attached to the device as either an input or an output. The device operates over a wide range of data rates from 125 Mbps to 2.97 Gbps (DC to 2.97 Gbps when driving cable) and supports ST 424, ST 292, ST 344, and ST 259. The return loss network is integrated within the device so no external ponents are required to meet the SMPTE return loss specification. The LMH0387 offers designers flexibility in system design and quicker time to market. In the input mode, the LMH0387 features include a power-saving sleep mode, programmable output mon mode voltage and swing, cable...
