OPERATION

(XT OR HS MODE)

Note 1: Quartz

crystal

characteristics

vary

according to type, package and manufac-

turer.

The

user

should

consult

the

manufacturer data sheets for specifica-

tions and recommended application.

2: Always verify oscillator performance over

the VDD and temperature range that is

expected for the application.

Note 1: A series resistor (RS) may be required for

quartz crystals with low drive level.

2: The value of RF varies with the oscillator

mode selected (typically between 2 M

Ω to

10 M

Ω).

3: If using LP mode and T1OSC in enable,

the LP oscillator will continue to run during

Sleep.

Note 1: A series resistor (RS) may be required for

ceramic resonators with low drive level.

2: The value of RF varies with the oscillator

mode selected (typically between 2 M

Ω to

10 M

Ω).

3: An additional parallel feedback resistor

(RP) may be required for proper ceramic

resonator operation (typical value 1 M

Ω).
