NOTES:
1. Includes filter feedback capacitance, comparator input capacitance. PCB stray capacitances and switch input capacitance.
2. Demodulator output DC coupled with Post Detection Filter Amplifier input and the demodulator tank exactly tuned to center frequency.
3. Includes DC offsets due to frequency offsets between Rx and Tx carrier and demodulator tank offset due to mis-tuning.
4. With a 400mV
P-P
sinusoid at 600kHz driving Pin 10. Output load resistance 500
in series with 10nF.
5. With a DC input and capacitor in the RC load fully charged.
6. The switch is closed every 10ms for a duration of 40
μ
s. The DC offset is determined by calculating the difference of 2 DC measurements,
which are determined as follows: 1) The first DC value is measured at the integrating capacitor of the switch when the switch is in the closed
position immediately before it opens. The value to be measured is in the middle of the peak-to-peak excursion of the superimposed
sine-wave. (DClow + (DChigh – DClow)/2). 2) The second DC value (calculated as above) is measured at Pin 11 immediately after the
switch opens, and is the DC value which gives the largest DC offset to the first DC measurement within a 400
μ
s DECT burst. Minimum and
maximum limits are not tested, however, they are guaranteed by design and characterization using an optimized layout and application
circuit.
7. Standard deviations are measured based on application of 60 parts.
