Its simple ceramic case totally eliminates coplanarity problems and also makes the transformers extremely economical. The VD9233-B has been optimized for use with Broadcom and other VDSL chip sets. Custom versions are also available to fit specific applications. For free evaluation samples, contact Coilcraft or visit the Coilcraft web site.
