How well does the DS92LV18 perform in cable drive applications?
The DS92LV18 can be used in cable drive applications with limited capability. If employed to transmit data across a generic category 5 cable, it can operate at its highest operating frequency (66 MHz) with cable lengths up to 10 ft. To transmit the data across longer links, cables with lower nominal attenuation are required. The Belden 89207 20 AWG twin-ax cable has proven to be a solid performer. At 66 MHz operation (1.32 Gbps data rate), the DS92LV18 can drive the Belden 89207 cable up to 20 ft. Careful interconnect design should be implemented to maximize the cable drive capabilities of the DS92LV18. Selecting controlled impedance cables and connectors greatly enhances the chance for an error-free data transfer.
