The LMH0394 3-Gbps HD/SD SDI Low Power Extended Reach 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 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. The LMH0394 includes power management to further reduce power consumption when no input signal is present.
The LMH0394 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. In SPI mode, an optional SPI serial interface can be used to access and configure multiple LMH0394 devices in a daisy-chain configuration. This allows users to program the output common-mode voltage and swing, output de-emphasis level, input launch amplitude, and power management settings. Users may also access a cable length indicator and all pin mode features.
