Equivalent Circuit Block Diagram
Multinetwork PLL (Automatic Adjustment Control)
The LA7583’s PIF detector uses a multinetwork PLL and a buzz canceller. The multinetwork PLL is a PLL detector that was
developed in order to eliminate the need for adjustments in video detection.
This PLL detector offers the following features:
(1) Eliminates the need for adjustments in video detection.
(2) The PLL detection characteristics are unaltered.
a. Offers better waveform response characteristics in comparison with the quasi-synchronous detection method.
b. The harmonic wave component of the video signal (demodulated output) is reduced.
c. The 1/2 IF signal suppression ratio is improved.
(3) Audio buzz is greatly reduced by the buzz canceller.
A typical PLL detector consists of the blocks shown below.
In these blocks, if the VCO coil is not adjusted to the IF frequency, a phase difference will appear in the control loop. As a result,
the PLL detector detection axis will shift from the ideal 180 °. The group delay, DP characteristics, etc., deteriorate as a result.
