Truth Table
1. DCS/PCS_TX, DCS_RX and PCS_RX paths can be turned off
simultaneously. Apply a VCC voltage to the DCS/PCS_TX path. Set control
voltages as shown in the truth table. Chosen path is EGSM_TX. All other
paths are in the off condition.
2. VCC voltage must be applied 10 ns (min.) before application of control
voltages (VC1, VC2).
