Description
The GS9064A is a second-generation high-speed
BiCMOS integrated circuit designed to equalize and
restore signals received over 75Ω co-axial cable.
The GS9064A is designed to support SMPTE 259M,
and is optimized for performance at 270Mb/s.
The GS9064A features DC restoration to compensate
for the DC content of SMPTE pathological test patterns.
The device also incorporates a Cable Length Indicator
(CLI) that provides an indication of the amount of cable
being equalized.
A voltage programmable mute threshold (MCLADJ) is
included to allow muting of the GS9064A output when
an approximate selected cable length is reached for
SMPTE 259M signals. This feature allows the GS9064A
to distinguish between low amplitude SD-SDI signals
and noise at the input of the device.
The bidirectional CD/MUTE pin indicates the presence
of a valid signal at the input of the GS9064A in addition
to functioning as a mute control input. The outputs of the
GS9064A will be forced to a mute state when an invalid
input reference signal is applied to the input of the
device or the application layer sets the CD/MUTE pin
HIGH. If the application layer forces CD/MUTE LOW,
the serial digital output of the device will always be
active.
Power consumption is typically 265mW using a 3.3V
power supply.
The GS9064A is Pb-free, and the encapsulation
compound does not contain halogenated flame
retardant (RoHS Compliant).
