5 TI Recommended PoC Networks

This section provides multiple TI recommended PoC networks. TI recommends selecting a network based on the desired frequency range, current rating, and temperature. Please note, each of these networks have been tested by TI to meet the channel specification requirements of the PCB budget using a minimal coupon test board. However, due to system dependent factors such as additional traces, touching components, the chosen connector, and general layout techniques, any chosen PoC network must be re-validated to verify that the insertion loss and return loss requirements are still met by the system.
