3 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 ST 424, ST 292, ST 344, and ST 259
standards.
The LMH0384 device 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.
