MC145152-2 Parallel-Input (Interfaces with
Dual-Modulus Prescalers)
The MC145152-2 is programmed by sixteen parallel inputs for the N and A counters and three input lines
for the R counter. The device features consist of a reference oscillator, selectable-reference divider,
two-output phase detector, 10-bit programmable divide-by-N counter, and 6-bit programmable
divide-by-A counter.
The MC145152-2 is an improved-performance drop-in replacement for the MC145152-1. Power
consumption has decreased and ESD and latch-up performance have improved.
