The R390 ran at 200 KHz and divided by two, but that’s an oddball. After the fact they figured out that the approach really did not improve things.
Actually, it was the later R390A that used a 200kHz crystal and divided by two. The original (earlier) R390 used a 1MHz crystal and divided by 10. In both cases, the "division" was accomplished by injection locking an astable multivibrator running with a natural period of ~100kHz.
