Multistandard hybrid IF processing
[3]
Output current can be increased by application of single-ended resistor from each output pin to GND. Recommended resistor value is
minimum 1 k
.
[4]
With single-ended load for fIF < 45 MHz RL ≥ 1k and CL ≤ 5 pF to ground and for fIF = 45 MHz to 60 MHz RL =1k and CL ≤ 3 pF to
ground.
[5]
Noise level is measured without input signal but AGC adjusted corresponding to the given input level.
[6]
Set with AGC nominal output voltage as reference. For C/N measurement switch input signal off.
[7]
With single-ended load RL ≥ 1k and CL ≤ 5 pF to ground.
[8]
The tolerance of the reference frequency determines the accuracy of VIF AFC, RIF AFC, FM demodulator center frequency, maximum
FM deviation, sound trap frequency, LIF band-pass cut-off frequency and ZIF low-pass cut-off frequency as well as the accuracy of the
synthesizer.
[9]
The value of Cpull determines the accuracy of the resonance frequency of the crystal. It depends on the used type of crystal.
[1]
Calculation of the PLL loop lter by using the following formulae, valid under the condition for the damping
factor d
≥ 1.2.
and
with the following
parameters
KO = VCO steepness (MHz/V),
N = divider ratio:
,
KD = phase frequency detector steepness (A/rad),
RLFSYN2 = synthesizer loop lter serial resistor (),
CLFSYN2 = synthesizer loop lter serial capacitor (F),
BLF(3dB) = 3 dB LF bandwidth (Hz),
d = damping factor.
[2]
If more than one frequency range is used in the application, then the smallest resistor value should be
applied.
