Interfaces with Dual–Modulus Prescalers

The MC145152–2 is programmed by sixteen parallel inputs for the N and A

counters and three input lines for the R counter. The device features consist of

a reference oscillator, selectable–reference divider, two–output phase detector,

10–bit programmable divide–by–N counter, and 6–bit programmable ÷ A

counter.

The MC145152–2 is an improved–performance drop–in replacement for the

MC145152–1. Power consumption has decreased and ESD and latch–up

performance have improved.

• Operating Temperature Range: – 40 to 85°C

• Low Power Consumption Through Use of CMOS Technology

• 3.0 to 9.0 V Supply Range

• On– or Off–Chip Reference Oscillator Operation

• Lock Detect Signal

• Dual Modulus/Parallel Programming

• 8 User–Selectable ÷ R Values: 8, 64, 128, 256, 512, 1024, 1160, 2048

• ÷ N Range = 3 to 1023, ÷ A Range = 0 to 63

• Chip Complexity: 8000 FETs or 2000 Equivalent Gates

• See Application Note AN980
