Description The LMH0384 3 Gbps HD/SD SDI Extended Reach and Configurable Adaptive Cable Equalizer is designed to equalize data transmitted over cable (or any media with similar dispersive loss characteristics). The equalizer operates over a wide range of data rates from 125 Mbps to 2.97 Gbps and supports SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE 259M standards. The LMH0384 includes active sensing features and design enhancements including longer cable equalization, lower output jitter, configurable pin mode and SPI modes, a power-saving sleep mode, and programmable output common mode voltage and swing. The LMH0384 implements DC restoration to correctly handle pathological data conditions. The LMH0384 includes an auto sleep mode to power down the device when no input signal is detected. Other features include separate carrier detect and output mute pins which may be tied together to mute the output when no input signal is present, and a programmable mute reference which may be used to mute the output at a selectable level of signal degradation. The LMH0384 supports two modes of operation. In pin mode (non-SPI mode) the LMH0384 is footprint compatible with the LMH0344 and legacy SDI equalizers. In the optional SPI mode, the LMH0384 provides register access to all of its features along with a cable length indicator, programmable output common mode voltage and swing, and launch amplitude optimization. The device is available in a 16-pin LLP package. Applications • SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE 259M serial digital interfaces • Serial digital data equalization and reception • Data recovery equalization

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
