POWER SUPPLY
5A6
VIO
I/O Logic-Level Translator Voltage. Bypass VIO to GND with a 0.1F ceramic
capacitor. VIO powers the logic inputs/outputs and I2C block.
23
F6
VTM
USB Analog Switch and Transceiver Power Supply. Bypass VTM to GND with a 0.1F
ceramic capacitor.
38
B1, B2
CLDO
Bypass Capacitor for Internal +1.8V LDO. Connect a 1F ceramic capacitor (X7R,
X5R, or better) from CLDO to GND. CLDO must not be used to power external
circuitry.
39
B3, C3
VCC
Digital Supply Voltage. Bypass VCC to GND with a 1F ceramic capacitor (X7R, X5R,
or better).
