MC145159-1

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Serial-Input PLL Frequency Synthesizer with Analog Phase Detector Interfaces with Dual–Modulus Prescalers The MC145159–1 has a programmable 14–bit reference counter, as well as fully programmable divide–by–N/divide–by–A counters. The counters are programmed serially through a common data input and latched into the appropriate counter latch, according to the last data bit (control bit) entered. When combined with a loop filter and VCO, this device can provide all the remaining functions for a PLL frequency synthesizer operating up to the device’s frequency limit. For higher VCO frequency operations, a down mixer or a dual–modulus prescaler can be used between the VCO and the PLL. 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 Compatible with the Serial Peripheral Interface (SPI) on CMOS MCUs ÷ R Range = 3 to 16383 ÷ N Range = 16 to 1023, ÷ A Range = 0 to 127 High–Gain Analog Phase Detector See Application Note AN969 Order this document by MC145159–1/D MC145159-1 20 1 P SUFFIX PLASTIC DIP CASE 738 20 1 DW SUFFIX SOG PACKAGE CASE 751D VF SUFFIX SSOP CASE TBD ORDERING INFORMATION MC145159P1 Plastic DIP MC145159DW1 SOG Package MC145159VF1 SSOP PIN ASSIGNMENTS PLASTIC DIP AND SOG PACKAGE RO OSCin OSCout CHARGE VDD FSO VSS MC LD fin 1 2 3 4 5 6 7 8 9 10 20 RR 19 VDD′ 18 CH 17 APDout 16 VSS′ 15 CR 1...
