The GS9064 is a second-generation high-speed bipolar integrated circuit designed to equalize and restore signals received over 75 Ohm co-axial cable at data rates from 143Mb/s up to 540Mb/s. The GS9064 is designed to support SMPTE 344M and SMPTE 259M and is optimized for performance at 270Mb/s.
The GS9064 features DC restoration to compensate for the DC content of SMPTE pathological test patterns, and incorporates a Cable Length Indicator (CLI) that provides a linear indication of the amount of cable being equalized.
A voltage programmable mute threshold (MCLADJ) is included to allow muting of the GS9064 output when a selected cable length is reached. This feature allows the GS9064 to distinguish between low amplitude SDI signals and noise at the input of the device. The CD/MUTE pin provides an indication of the GS9064 mute status in addition to functioning as a mute control input. The output of the GS9064 may be forced to an active or a mute condition by applying a voltage to the CD/MUTE pin.
SMPTE 259 and SMPTE 344 compliant
