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.

The ML145146 is programmed by a 4–bit input, with

• Operating Temperature Range: T A – 40 to +85°C

• Low Power Consumption Through the Use of

• 3.0 to 9.0 V Supply Range

• Programmable Reference Divider for Values Between

• Dual–Modulus 4–Bit Data Bus Programming

• ÷ N Range = 3 to 1023, ÷ A Range= 0 to 127

• “Linearized” Digital Phase Detector Enhances

• Two Error Signal Options:
