4-Bit Data Bus Input PLL Frequency Synthesizer

Interfaces with Dual–Modulus Prescalers

The MC145146–2 is programmed by a 4–bit input, with strobe and address lines. The device features consist of a reference oscillator, 12–bit programmable reference divider, digital phase detector, 10–bit programmable divide–by–N counter, 7–bit divide–by–A counter, and the necessary latch circuitry for accepting the 4–bit input data.
