FEATURES DESCRIPTION 2 The LMH0307 3 Gbps HD/SD SDI Dual Output Cable • SMPTE 424M， SMPTE 292M， SMPTE 344M， and Driver with Cable Detect is designed for use in SMPTE 259M Compliant SMPTE 424M， SMPTE 292M， SMPTE 344M， and • Data Rates to 2.97 Gbps SMPTE 259M serial digital video applications. The • Supports DVB-ASI at 270 Mbps LMH0307 implements two complementary output drivers and drives 75Ω transmission lines （Belden • Cable Detect on Output 1694A， Belden 8281， or equivalent） at data rates up • Loss of Signal Detect at Input to 2.97 Gbps. • Output Driver Power Down Control The LMH0307 includes intelligent sensing capabilities • Typical Power Consumption： 230 mW in SD to improve system diagnostics. The cable detect Mode and 275 mW in HD Mode feature senses near-end termination to determine if a • Power Save Mode Typical Power cable is correctly attached to the output BNC. Input Consumption： 4 mW loss of signal （LOS） detects the presence of a valid signal at the input of the cable driver. These sensing • Single 3.3V Supply Operation features may be used to alert the user of a system • Differential Input fault and activate a deep power save mode， reducing • Dual Complementary 75Ω Outputs the cable driver‘s power consumption to 4 mW. These features are accessible via an SMBus interface. • Selectable Slew Rate • Industrial Temperature Range： −40°C to +85°C The LMH0307 provides two selectable slew rates for SMPTE 259M and SMPTE 424M / 292M compliance. • 16-Pin WQFN or 25-Ball CS-BGA package The output amplitude is adjustable ±10% in 5 mV steps via the SMBus. APPLICATIONS The LMH0307 is powered from a single 3.3V supply. • SMPTE 424M， SMPTE 292M， SMPTE 344M， and Power consumption is typically 230 mW in SD mode SMPTE 259M Serial Digital Interfaces and 275 mW in HD mode. The LMH0307 is available • Digital Video Routers and Switches in two space-saving packages： a 4 x 4 mm 16-pin WQFN and even more space-efficient 3 x 3 mm 25- • Distribution Amplifiers ball CS-BGA package.
