9 / 36 page MC145151–2 through MC145158–2 MOTOROLA 9 Serial-Input PLL Frequency Synthesizer Interfaces with Single–Modulus Prescalers The MC145155–2 is programmed by a clocked, serial input, 16–bit data stream. The device features consist of a reference oscillator, selectable–refer- ence divider, digital–phase detector, 14–bit programmable divide–by–N counter, and the necessary shift register and latch circuitry for accepting serial input data. The MC145155–2 is an improved–performance drop–in replacement for the MC145155–1. 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 with Buffered Output • Compatible with the Serial Peripheral Interface (SPI) on CMOS MCUs • Lock Detect Signal • Two Open–Drain Switch Outputs • 8 User–Selectable ÷ R Values: 16, 512, 1024, 2048, 3668, 4096, 6144, 8192 • Single Modulus/Serial Programming • ÷ 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: 6504 FETs or 1626 Equivalent Gates MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC145155-2 P SUFFIX PLASTIC DIP CASE 707 DW SUFFIX SOG PACKAGE CASE 751D ORDERING INFORMATION MC145155P2 Plastic DIP MC145155DW2 SOG Package PIN ASSIGNMENTS VDD φV RA2 RA1 fin LD VSS PDout φR REFout OSCout OSCin RA0 CLK DATA ENB SW1 SW2 14 15 16 17 18 10 11 12 13 5 4 3 2 1 9 8 7 6 PLASTIC DIP PDout φR φV RA2 RA1 fin LD NC VSS VDD 5 4 3 2 1 10 9 8 7 6 14 15 16 17 18 19 20 11 12 13 NC REFout OSCout OSCin RA0 CLK DATA ENB SW1 SW2 SOG PACKAGE NC = NO CONNECTION 1 18 20 1 © Motorola, Inc. 1995 REV 1 8/95 |
