7 / 24 page MC145152-2 Parallel-Input (Interfaces with Dual-Modulus Prescalers) MC145151-2 and MC145152-2 Technical Data, Rev. 5 Freescale Semiconductor 7 2 MC145152-2 Parallel-Input (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 divide-by-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. 2.1 Features • 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 Figure 5.
