Document 319-1 MagneticsfortheInfineonGEMINAX This product is not RoHS-compliant. Contact Coilcraft for current status or possible alternatives. The Coilcraft A9807-A ADSL transformer and A9806-A low-pass inductor are designed specifically for Infineon’s GEMINAX ADSL chipset for use in CO, DLC, and DSLAM linecard applications. The A9807-A is the main component of the high-pass filter section ensuring that low-frequency, high-level POTS signals do not enter the ADSL front end components. The A9806-A inductor is the low-pass filter in the Integrated Voice and Data (IVD) GEMINAX chipset. For free evaluation samples contact Coilcraft or visit www. coilcraft.com.
