GS1574集成电路（IC）的视频处理规格书PDF中文资料

描述 Description

The GS1574 is a second-generation high-speed bipolar integrated circuit designed to equalize and restore signals received over 75Ω co-axial cable.

The GS1574 is designed to support SMPTE 292M, SMPTE 344M and SMPTE 259M, and is optimized for performance at 270Mb/s and 1.485Gb/s.

The GS1574 features DC restoration to compensate for the DC content of SMPTE pathological test patterns.

特性 Features

• SMPTE 292M, SMPTE 344M and SMPTE 259M compliant

• Small footprint (4mm x 4mm)

• Pb-free and RoHS Compliant

• Pin compatible with the GS9074 Cable Equalizer

• Manual bypass (useful for low data rates with slow rise/fall times)

• Performance optimized for 270Mb/s and 1.485Gb/s

• Typical maximum equalized length of Belden 1694A cable: 140m 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

• 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.
