FX604
Operating Characteristics
For the following conditions unless otherwise specified:
V_DD = 3.0V at Tamb = 25°C and V_DD = 3.3V to 5.5V at Tamb = -40 to +85°C,
Xtal Frequency = 3.579545MHz ± 0.1%
0dBV corresponds to 1.0Vrms
0dBm corresponds to 775mVrms into 600Ω.
DC Parameters
I_DD (M0='1', M1='1')
I_DD (M0 or M1='0') at V_DD = 3.0V
I_DD (M0 or M1='0') at V_DD= 5.0V
