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.

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.
