If the unlocked state is detected during a channel change, the PDS (sub-charge pump) operates, R1
← R1M/R1S, the
low-pass filter time constant is reduced, and lockup is accelerated.
* Unlock detection data: UL1 = 1 must be set. This sets the unlock detection width to “±0.5
s” or “±1 s” mode; if a
phase difference that is greater than the value in question is detected, the signal is unlocked and the sub-charge pump
operates. As the locked condition is approached and the phase difference falls to less than the unlocked detection
width, the sub-charge pump stops operating (goes to high impedance).
* Since the PLL block in the LA17000M does not provide an
external pin for ADI1, the function cannot be used. ADI0
is linked directly to the pin 34 MRC sensor output, and is
used exclusively for multipath signal intensity detection.
