2 / 24 page MC145151-2 and MC145152-2 Technical Data, Rev. 5 2 Freescale Semiconductor MC145151-2 Parallel-Input (Interfaces with Single-Modulus Prescalers) 1 MC145151-2 Parallel-Input (Interfaces with Single-Modulus Prescalers) The MC145151-2 is programmed by 14 parallel-input data lines for the N counter and three input lines for the R counter. The device features consist of a reference oscillator, selectable-reference divider, digital-phase detector, and 14-bit programmable divide-by-N counter. The MC145151-2 is an improved-performance drop-in replacement for the MC145151-1. The power consumption has decreased and ESD and latch-up performance have improved. 1.1 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 • ÷ N Counter Output Available • Single Modulus/Parallel Programming • 8 User-Selectable ÷ R Values: 8, 128, 256, 512, 1024, 2048, 2410, 8192 • ÷ N Range = 3 to 16383 • “Linearized” Digital Phase Detector Enhances Transfer Function Linearity • Two Error Signal Options: Single-Ended (Three-State) or Double-Ended • Chip Complexity: 8000 FETs or 2000 Equivalent Gates Figure 1.
