The LMH0303 device is designed for use in ST 424, ST 292, ST 344, and ST 259 serial digital video applications. The LMH0303 drives 75-Ω transmission lines (Belden 1694A, Belden 8281, or equivalent) at data rates up to 2.97 Gbps.
●The LMH0303 includes intelligent sensing capabilities to improve system diagnostics. The cable detect feature senses near-end termination to determine if a cable is correctly attached to the output BNC. Input loss of signal (LOS) detects the presence of a valid signal at the input of the cable driver. These sensing features may be used to alert the user of a system fault and activate a deep power-save mode, reducing the power consumption of the cable driver to 4 mW. These features are accessible through an SMBus interface.
●The LMH0303 provides two selectable slew rates for ST 259 and ST 424 or 292. The output amplitude is adjustable ±10% in 5-mV steps through the SMBus.
●The LMH0303 is powered from a single 3.3-V supply. Power consumption is typically 130 mW in SD mode and 155 mW in HD mode. The LMH0303 is available in a 16-pin WQFN package.
