NXP Semiconductors MC145151-2

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.
