AC ELECTRICAL CHARACTERISTICS (continued)
(Typical Application Circuit, V DD = 3.0V to 3.6V, all RF inputs are referenced to 50 ? , f RF = 315MHz, T A = -40°C to +85°C, unless
otherwise noted. Typical values are at V DD = 3.3V and T A = +25°C.) (Note 1)

Note 1: 100% tested at T A = +25 ° C. Guaranteed by design and characterization over temperature.
Note 2: IRSEL is internally set to 375MHz IR mode. It can be left open when the 375MHz image rejection setting is desired. A 1nF
capacitor is recommended in noisy environments.
Note 3: BER = 2 x 10 -3 , Manchester encoded, data rate = 4kbps, IF bandwidth = 280kHz.
Note 4: Input impedance is measured at the LNAIN pin. Note that the impedance includes the 15nH inductive degeneration con-
nected from the LNA source to ground. The equivalent input circuit is 50 ? in series with 2.2pF.
Note 5: Crystal oscillator frequency for other RF carrier frequency within the 300MHz to 450MHz range is (f RF - 10.7MHz)/64 for
XTALSEL = 0V, and (f RF - 10.7MHz)/32 for XTALSEL = V DD .
