GS1524A

GS1524A Adaptive Cable Equalizer Features SMPTE 292M, SMPTE 344M and SMPTE 259M compliant Automatic cable equalization Multi-standard operation from 143Mb/s to 1.485Gb/s Supports DVB-ASI at 270Mb/s Pb-free and RoHS Compliant Pin compatible with the GS9064 Cable Equalizer Manual bypass (useful for low data rates with slow rise/fall times) Performance optimized for 270Mb/s and 1.485Gb/s Typical equalized length of Belden 1694A cable: 200m at 1.485Gb/s, 350m at 270Mb/s 50Ω differential output (with internal 50Ω pull-ups) Manual output mute or programmable mute based on max cable length adjust Cable length indicator for SMPTE 259M inputs Single 3.3V power supply operation Operating temperature range: 0°C to +70°C Applications SMPTE 292M, SMPTE 344M and SMPTE 259M Coaxial Cable Serial Digital Interfaces. Description The GS1524A is a second-generation high-speed BiCMOS integrated circuit designed to equalize and restore signals received over 75Ω co-axial cable. The GS1524A is designed to support SMPTE 292M, SMPTE 344M and SMPTE 259M, and is optimized for performance at 270Mb/s and 1.485Gb/s. The GS1524A 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 for data rates up to 360Mb/s. A voltage programmable mute threshold (MCLADJ) is included to allow muting of the GS1524A output when ...
