Description
The GS1574A is a second-generation high-speed
BiCMOS integrated circuit designed to equalize and
restore signals received over 75Ω co-axial cable.
The GS1574A is designed to support SMPTE 292M and
SMPTE 259M, and is optimized for performance at
270Mb/s and 1.485Gb/s.
The GS1574A features DC restoration to compensate
for the DC content of SMPTE pathological test patterns.
A voltage programmable mute threshold (MCLADJ) is
included to allow muting of the GS1574A output when
an approximate selected cable length is reached for
SMPTE 259M signals. This feature allows the GS1574A
to distinguish between low amplitude SD-SDI signals
and noise at the input of the device. The serial digital
outputs of the GS1574A may be forced to a mute state
by applying a voltage to the MUTE pin.
Power consumption is typically 215mW using a 3.3V
power supply. The GS1574A is lead-free, and the
encapsulation compound does not contain halogenated
flame retardant.
This component and all homogeneous subcomponents
are RoHS compliant.
