GS9064A HD-LINX II Adaptive Cable Equalizer GS9064A Data Sheet Features Description SMPTE 259M compliant The GS9064A is a second-generation high-speed BiCMOS integrated circuit designed to equalize and Automatic cable equalization restore signals received over 75 co-axial cable. Supports DVB-ASI at 270Mb/s The GS9064A is designed to support SMPTE 259M, Pb-free and RoHS compliant and is optimized for performance at 270Mb/s. Manual bypass (useful for low data rates with slow rise/fall times) The GS9064A features DC restoration to compensate for the DC content of SMPTE pathological test patterns. Performance optimized for 270Mb/s The device also incorporates a Cable Length Indicator Typical maximum equalized length of Belden (CLI) that provides an indication of the amount of cable 1694A cable: 350m at 270Mb/s being equalized. 50 differential output (with internal 50 pull-ups) A voltage programmable mute threshold (MCLADJ) is Manual output mute or programmable mute based included to allow muting of the GS9064A output when on max cable length adjust an approximate selected cable length is reached for Cable length indicator for SMPTE 259M inputs SMPTE 259M signals. This feature allows the GS9064A Single 3.3V power supply operation to distinguish between low amplitude SD-SDI signals and noise at the input of the device. Operating temperature range: 0C to +70C The bidirectional CD/MUTE pin indicates the presence Applications of a valid signal at the input of the GS9064A in addition SMPTE 259M Coaxial Cable Serial Digital to functioning as a mute control input. The outputs of the Interfaces. GS9064A will be forced to a mute state when an invalid input reference signal is applied to the input of the device or the application layer sets the CD/MUTE pin HIGH. If the application layer forces CD/MUTE LOW, the serial digital output of the device will always be active. Power consumption is typically 265mW using a 3.3V power supply. The GS9064A is Pb-free, and the encapsulation compound does not contain halogenated flame retardant (RoHS Compliant). 37325 - 0 December 2005 1 of 16 www.gennum.comGS9064A Data Sheet CABLE LENGTH INDICATOR/ADJUSTOR CLI CARRIER DETECT MCLADJ CD/MUTE MUTE BYPASS SDO SDI EQUALIZER DC RESTORE OUTPUT SDI SDO AGC GS9064A Functional Block Diagram Contents Features ........................................................................................................................1 Applications...................................................................................................................1 Description ....................................................................................................................1 1.
