ML145146 4–Bit Data Bus Input PLL Frequency Synthesizer INTERFACES WITH DUAL–MODULUS PRESCALERS Legacy Device: Motorola MC145146-2 The ML145146 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: TA – 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 P DIP 20 = RP PLASTIC DIP CASE 738 1 20 20 SOG 20 W = -6P SOG PACKAGE CASE 751D 1 CROSS REFERENCE/ORDERING INFORMATION PACKAGE MOTOROLA LANSDALE P DIP 20 MC145146P2 ML145146RP SOG 20W MC145146DW2 ML145146-6P Note: Lansdale lead free (Pb) product, as it becomes available, will be identified by a part number prefix change from ML to MLE.
