3 Gbps HD/SD SDI Adaptive Cable Equalizer
General Description
The LMH0344 3 Gbps HD/SD SDI Adaptive Cable Equalizer
is designed to equalize data transmitted over cable (or any
media with similar dispersive loss characteristics). The equal-
izer 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.
The LMH0344 implements DC restoration to correctly handle
pathological data conditions. The equalizer may be driven in
either a single ended or differential configuration.
Additional features include separate carrier detect and output
mute pins which may be tied together to mute the output when
no signal is present. A programmable mute reference is pro-
vided to mute the output at a selectable level of signal degra-
dation.
The device is available in two space–saving packages: a 4 X
4 mm 16-pin LLP and even more space–efficient 3 x 3 mm
25-ball MICRO-ARRAY package.
