AC Electrical Characteristics (continued)
(Typical Application Circuit, VDD5 = +4.5V to +5.5V, all RF inputs are referenced to 50Ω, fRF = 433.92MHz, TA = -40°C to +125°C,
unless otherwise noted. Typical values are at VDD5 = +5.0V and TA = +25°C.) (Note 1)

Note 1: 100% tested at TA = +125°C. Guaranteed by design and characterization over entire temperature range.
Note 2: IRSEL is internally set to 375MHz IR mode. It can be left open when the 375MHz image-rejection setting is desired. Bypass
to AGND with a 1nF capacitor in a noisy environment.
Note 3: Peak power level. BER = 2 x 10-3, Manchester encoded, data rate = 4kbps, IF bandwidth = 280kHz.
Note 4: The voltage conversion gain is measured with the LNA input matching inductor and the LNA/Mixer resonator in place, and
does not include the IF filter insertion loss.
Note 5: Crystal oscillator frequency for other RF carrier frequency within the 300MHz to 450MHz range is (fRF - 10.7MHz)/64 for
XTALSEL = 0V, and (fRF - 10.7MHz)/32 for XTALSEL = VDVDD.
