8. The lock indicator pin (LOCK) will reliably indicate a
MOTOROLA
phase–locked condition at SYNC input frequencies down
to 10MHz. At frequencies below 10MHz, the frequency of
correction pulses going into the phase detector form the
SYNC and FEEDBACK pins may not be sufficient to allow
the lock indicator circuitry to accurately predict a
phase–locked conditition. The MC88915T is guaranteed
to provide stable phase–locked operation down to the
appropriate minimum input frequency given in Table 1,
even though the LOCK pin may be LOW at frequencies
below 10MHZ. The exact minimum frequency where the
lock indicator functionality can be guaranteed will be
available when the MC88915T reaches ‘MC’ status.
