Voltage Translation Description
The FXLA2203 provides full voltage translation, or level
shifting, from 1.65V – 3.6V between Host 1 or Host 2
and either SIM card (according to Table 3). The host
sides reference VCC_H_1 and VCC_H_2, respectively, while
each SIM slot references the external PMIC LDO
voltage level determined by the CH_Swap pin. This
architecture offers a flexible solution for problematic VCC
domain disagreements. For example, if Host 1 operates
at 1.65V and Host 2 operates at 2.5V, while slot 1 is
populated with a 3.0V SIM card and slot 2 is populated
with a 1.8V SIM card, the FXLA2203 provides seamless
voltage translation across all four VCC domains.
