Note 1:
Production tested at T
A
= +85°C. Guaranteed by design and characterization over entire temperature range.
Note 2:
Guaranteed by design and characterization. Not production tested.
Note 3:
The oscillator register (0x3) is set to the nearest integer result of f
XTAL
/ 100kHz (see the
Oscillator Frequency Register
section).
Note 4:
Input impedance is measured at the LNAIN pin. Note that the impedance at 315MHz includes the 15nH inductive degeneration
from the LNA source to ground. The impedance at 434MHz includes a 10nH inductive degeneration connected from the LNA
source to ground. The equivalent input circuit is 50
in series with 2.2pF. The voltage conversion gain is measured with the
LNA input matching inductor, the degeneration inductor, and the LNA/mixer resonator in place, and does not include the IF fil-
ter insertion loss.
