LMH0303SQE/NOPB

具有电缆检测的 3Gbps HD/SD SDI 电缆驱动器 16-WQFN -40 to 85

The is a 3Gbps HD/SD SDI Cable Driver with Cable Detect is designed for use in SMPTE 424M, SMPTE 292M, SMPTE 344M and SMPTE 259M serial digital video applications. The LMH0303 drives 75R transmission lines Belden 1694A, Belden 8281 or equivalent at data rates up to 2.97Gbps. 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 cable driver"s power consumption to 4mW. These features are accessible via an SMBus interface. It provides two selectable slew rates for SMPTE 259M and SMPTE 424M/292M compliance. The output amplitude is adjustable ±10% in 5mV steps via the SMBus.
