With SLIC-E/-E2/-P external ringing is supported, however for US market with external
ringing, the SLIC-LCP is the most suitable device, as it also provides an automatic
longitudinal balance adaptation. This reduces BOM cost while maintaining a very good
longitudinal balance.

Table 17
Note).
Note: For stability reasons, PCB must be designed with minimum parasitic capacitances
