The four-wire to four-wire gain, G
balance network
When selecting the
terminal is at least 20 k .
If calculation of the Z
please contact Infineon‘s support group for assistance.
The PBL 38620/2 SLIC may also be used together with programmable CODEC/filters.
The programmable CODEC/filter allows for system controller adjustment of hybrid
balance to accomodate different line impedances without change of hardware. In
addition, the transmit and receive gain may be adjusted. Please, refer to the
programmable CODEC/filter data sheets for design information.
