G S 90 68 S D SDI Cable Driver
DATA SHEET KE Y FEATURES · SMPTE 259M and SMPTE 344M compliant · dual coaxial cable driving outputs · 50 differential PECL input · single 3.3V power supply operation · space-saving 8-lead SOIC · operating temperature range: 0°C to 70°C · pin compatible with GS1528 HD-LINXTM II multirate SDI dual slew-rate cable driver A P P LI C A T I O N S · SMPTE 259M Coaxial Cable Serial Digital Interfaces D E S C R I P TI O N The GS9068 is a second generation high-speed bipolar integrated circuit designed to drive one or two 75 co-axial cables at data rates up to 540Mb/s. The GS9068 accepts a LVPECL level differential input, which may be AC coupled. External biasing resistors at the inputs are not required. Power consumption is typically 160mW using a +3.3V DC power supply.
