A9806-A

Document 319-1
Magnetics for the Infineon GEMINAX
This product is not RoHS-compliant. Contact Coilcraft
for current status or possible alternatives.
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 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 A9806-A inductor is the low-pass filter in the Integrated Voice and Data (IVD) GEMINAX chipset.
