GS1574A HD-LINX II Adaptive Cable Equalizer Features Description SMPTE 292M and SMPTE 259M compliant The GS1574A is a second-generation high-speed BiCMOS integrated circuit designed to equalize and restore signals Automatic cable equalization received over 75 co-axial cable. Multi-standard operation from 143Mb/s to 1.485Gb/s The GS1574A is designed to support SMPTE 292M and Supports DVB-ASI at 270Mb/s SMPTE 259M, and is optimized for performance at 270Mb/s Small footprint (4mm x 4mm) and 1.485Gb/s. Pb-free and RoHS compliant The GS1574A features DC restoration to compensate for Manual bypass (useful for low data rates with slow the DC content of SMPTE pathological test patterns. rise/fall times) A voltage programmable mute threshold (MCLADJ) is Performance optimized for 270Mb/s and 1.485Gb/s included to allow muting of the GS1574A output when an Typical equalized length of Belden 1694A cable: 200m approximate selected cable length is reached for SMPTE at 1.485Gb/s, 350m at 270Mb/s 259M signals. This feature allows the GS1574A to 50 differential output (with internal 50 pull-ups) distinguish between low amplitude SD-SDI signals and Manual output mute or programmable mute based on noise at the input of the device. The serial digital outputs of max cable length adjust the GS1574A may be forced to a mute state by applying a voltage to the MUTE pin. Single 3.3V power supply operation Operating temperature range: 0C to +70C Power consumption is typically 215mW using a 3.3V power supply. The GS1574A is lead-free, and the Application encapsulation compound does not contain halogenated SMPTE 292M and SMPTE 259M Coaxial Cable Serial flame retardant. Digital Interfaces This component and all homogeneous subcomponents are RoHS compliant.
