MC145146DW2 phase lock loop pll frequency synthesizer

4 Bit Data Bus Input - PLL Frequency Synthesizer
in a 20 pin SO (SMT SMD) wided bodied package
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.
Operating Temperature Range: – 40 to 85°C
Low Power Consumption Through the Use of CMOS Technology
Programmable Reference Divider for Values Between 3 and 4095
Dual–Modulus 4–Bit Data Bus Programming
N Range = 3 to 1023, A Range = 0 to 127
“Linearized” Digital Phase Detector Enhances Transfer Function Linearity
