The G ENLINX TM GS9010A is a monolithic integrated circuit designed to be an Automatic Tuning Subsystem (ATS) when used with the GS9005A Receiver or the GS9015A Reclocker and the GS9000B or GS9000S Decoder. The GS9010A ATS eliminates the need to manually set or externally temperature compensate the Receiver or Reclocker VCO. The GS9010A can also determine whether the incoming data stream is 4sc NTSC, 4sc PAL or component 4:2:2.
