Interfaces with Single–Modulus Prescalers
The MC145145–2 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, 14–bit programmable divide–
by–N counter, and the necessary latch circuitry for accepting the 4–bit input
data.
Operating Temperature Range: – 40 to 85
°
