MC145151-2 Parallel-Input (Interfaces with Single-Modulus Prescalers)
1 MC145151-2 Parallel-Input (Interfaces with Single-Modulus Prescalers)
The MC145151-2 is programmed by 14 parallel-input data lines for the N counter and three input lines for the R counter. The device features consist of a reference oscillator, selectable-reference divider, digital-phase detector, and 14-bit programmable divide-by-N counter.
The MC145151-2 is an improved-performance drop-in replacement for the MC145151-1. The power consumption has decreased and ESD and latch-up performance have improved.
