Note 1: 100% tested at T
A
= +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 (f
RF
- 10.7MHz)/64 for
XTALSEL = 0V, and (f
RF
- 10.7MHz)/32 for XTALSEL = DV
