Power Supplies

VDDIO

3.3V digital supply. Digital power supply must

be decoupled by external capacitors

Power

3.0V to 3.6V

VDDIN

3.3V Digital LDO input supply

Power

3.0V to 3.6V

VDDIN AN

3.3V Analog LDO input supply

Power

3.0V to 3.6V

VDDOUT AN

1.2V Analog LDO output. A capacitor in the

range 0.1μF - 10μF must be connected to

each pin

Power

1.2V

VDDOUT

1.2V Digital LDO output. A capacitor in the

range 0.1μF - 10μF must be connected to

each pin

Power

1.2V

VDDPLL

1.2V PLL supply. It must be decoupled by a

100nF external capacitor, and connected to

VDDOUT through a filter (Cut off frequency:

25kHz)

Power

1.2V

GND(1)

Digital Ground

Power

AGND(1)

Analog Ground

Power

Clocks, Oscillators and PLLs

CLKEA(2)

External Clock Oscillator

• CLKEA must be connected to one terminal

of a crystal (when a crystal is being used) or

used as input for external clock signal

Input

VDDIO

CLKEB(2)

External Clock Oscillator

• CLKEB must be connected to one terminal

of a crystal (when a crystal is being used) or

must be floating when an external clock

signal is connected through CLKEA

I/O

VDDIO

CLKOUT

10MHz External Clock Output

Output

VDDIO

Reset/Test

ARST

Asynchronous Reset

Input

Low

VDDIO

Internal pull up(3)

SRST

Synchronous Reset

Input

Low

VDDIO

Internal pull up(3)

PLL INIT

PLL Initialization Signal

Input

Low

VDDIO

Internal pull up(3)

PPLC (PRIME Power Line Communications) Transceiver

EMIT [0:11](4)

PLC Tri-state Transmission ports

Output

VDDIO

AGC [0:5]

Automatic Gain Control:

• These digital tri-state outputs are managed

by AGC hardware logic to drive external

circuitry when input signal attenuation is

needed

Output

VDDIO
