The LMH0002 is a high-performance cable driver from National Semiconductor Corporation that complies with the SMPTE 292M / 259M standard. It supports 75-ohm transmission lines and has a transmission speed of up to 1.485 Gbps. The LMH0002 provides two selectable slew rates to meet SMPTE 259M and SMPTE 292M standards. The output voltage swing can be adjusted via a single external resistor. The LMH0002 is powered by a single 3.3V supply. Typical power consumption is 125mW (SD mode) and 149mW (HD mode).
The LMH0002 is a monolithic, high-speed cable driver designed for SMPTE 292M and 259M serial digital video and ITU-T G.703 serial digital data transmission applications. It drives 75Ω transmission lines at data rates up to 1.485 Gbps and features selectable slew rates for compliance with both SMPTE 259M and SMPTE 292M standards.
