4 BIT DATA BUS INPUT 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 program-
mable 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 3.0 to 9.0 V Supply Range 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 Two Error Signal Options:
Single–Ended (Three–State)
Double–Ended
