LMH0394SQE/NOPB, Специализированный интерфейс, SPI

The LMH0394SQE/NOPB is a 3Gbps HD/SD SDI Extended Reach Adaptive Cable Equalizer 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 125Mbps to 2.97Gbps and supports ST 424, ST 292, ST 344, ST 259 and DVB-ASI standards. The LMH0394 provides extended cable reach with improved immunity to crosstalk and ultra-low power consumption. The equalizer includes active sensing circuitry that ensures robust performance and enhanced immunity to variations in the input signal launch amplitude. The output driver offers programmable de-emphasis for up to 40" of FR4 trace losses. It includes power management to further reduce power consumption when no input signal is present. It supports two modes of operation. In pin mode, the LMH0394 operates with control pins to set its operating state and is footprint compatible with the LMH0384, LMH0344 and legacy SDI equalizers.
