8 / 140 page  FEDL7396A/B/E-07 ML7396A/B/E 8/140 ●Power supply pins Pin No Pin name Reset state I/O Active Level Detail function 14,18 VDDIO -/- PWR - Power supply for digital IOs (Input voltage: 1.8V to 3.3V) 40 VDD_REG -/- PWR - Power supply for regulator input (Input voltage: 1.8V to 3.3V) 29 VDD_PA -/- PWR - Power supply for PA block (Input voltage: 1.8V to.3.3V, depending on TX mode) 32 VDD_RF -/- PWR - Power supply for RF blocks (REG_OUT is connected, typ.1.5V) 23 VDD_IF -/- PWR - Power supply for IF block (REG_OUT is connected, typ.1.5V) 34 VDD_CP -/- PWR - Power supply for charge pump (REG_OUT is connected, typ.1.5V) 39 VDD_VCO -/- PWR - Power supply for VCO (REG_OUT is connected, typ.1.5V) EL - -/- GND - GND PAD ●Unused pins Unused pins treatments are as follows: Pin Name Pin number Recommended treatment XIN 4 Fixed to GND (When TCXO is used) XOUT 5 Fixed to GND (When TCXO is used) TCXO 6 Fixed to GND (When crystal OSC is used) ATEST1 25 Left OPEN ATEST2 26 Left OPEN A_MON 24 Left OPEN ANT_SW 20 Left OPEN DMON 17 Left OPEN *1 DCNT 22 Left OPEN *1 If not using DMON, it is necessary to stop clock out (default output on DMON) by CLKOUT_EN ([CLK_SET:B0 0x02(4)]). Left open with enableing clock out causes the perfoemance down on RX sensitivity. Note: If input pins are high-impedence state and leave open, excess current could be drawn. Care must be taken that unused input pins and unused I/O pins should not be left open. |
