13 / 36 page  MC145151–2 through MC145158–2 MOTOROLA 13 Serial-Input PLL Frequency Synthesizer Interfaces with Dual–Modulus Prescalers The MC145156–2 is programmed by a clocked, serial input, 19–bit data stream. The device features consist of a reference oscillator, selectable–refer- ence divider, digital–phase detector, 10–bit programmable divide–by–N counter, 7–bit programmable divide–by–A counter, and the necessary shift register and latch circuitry for accepting serial input data. The MC145156–2 is an improved–performance drop–in replacement for the MC145156–1. 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 • Dual Modulus/Serial Programming • 8 User–Selectable ÷ R Values: 8, 64, 128, 256, 640, 1000, 1024, 2048 • ÷ N Range = 3 to 1023, ÷ A Range = 0 to 127 • “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 MC145156-2 P SUFFIX PLASTIC DIP CASE 738 DW SUFFIX SOG PACKAGE CASE 751D ORDERING INFORMATION MC145156P2 Plastic DIP MC145156DW2 SOG Package PIN ASSIGNMENT PDout φR φV RA2 RA1 fin LD MC VSS VDD 5 4 3 2 1 10 9 8 7 6 14 15 16 17 18 19 20 11 12 13 TEST REFout OSCout OSCin RA0 CLK DATA ENB SW1 SW2 1 20 1 20 © Motorola, Inc. 1995 REV 1 8/95 |
