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
NOT RECOMMENDED FOR NEW DESIGNS;
PRODUCT TO BE PHASED OUT.
Closest equivalents are the MC145152–2, MC145170–1,
MC14519X series, and MC14520X series.
