1 / 12 page MC145159–1 MOTOROLA 1 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 PIN ASSIGNMENTS PLASTIC DIP AND SOG PACKAGE FSO CHARGE OSCout OSCin RO 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 VSS′ APDout CH VDD′ RR CLK DATA ENB SRout CR SSOP RO VDD′ CH APDout VSS′ VDD CHARGE OSCout OSCin RR 5 4 3 2 1 10 9 8 7 6 14 15 16 17 18 19 20 11 12 13 CLK DATA ENB SRout CR FSO VSS MC LD fin Order this document by MC145159–1/D MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC145159-1 P SUFFIX PLASTIC DIP CASE 738 DW SUFFIX SOG PACKAGE CASE 751D ORDERING INFORMATION MC145159P1 Plastic DIP MC145159DW1 SOG Package MC145159VF1 SSOP 20 1 VF SUFFIX SSOP CASE TBD 20 1 © Motorola, Inc. 1995 REV 1 8/95 |
