Order this document by MC44817/D MC44817/17B PLL Tuning Circuits with 3-Wire Bus The MC44817/17B are tuning circuits for TV and VCR tuner applications. They contain on one chip all the functions required for PLL control of a VCO. The integrated circuits also contain a high frequency prescaler and thus can handle frequencies up to 1.3 GHz. The MC44817 has programmable 512/1024 reference divider while the MC44817B has a fixed reference divider of 1024. The MC44817/17B are manufactured on a single silicon chip using Motorola’s high density bipolar process, MOSAIC™ (Motorola Oxide Self Aligned Implanted Circuits). TV AND VCR PLL TUNING CIRCUITS WITH 1.3 GHz PRESCALER AND 3–WIRE BUS SEMICONDUCTOR TECHNICAL DATA Complete Single Chip System for MPU Control (3–Wire Bus). Data and Clock Inputs are IIC Bus Compatible Divide–by–8 Prescaler Accepts Frequencies up to 1.3 GHz 15 Bit Programmable Divider Accepts Input Frequencies up to 165 MHz Reference Divider: Programmable for Division Ratios 512 and 1024. The MC44817B has a Fixed 1024 Reference Divider Tri–State Phase/Frequency Comparator Operational Amplifier for Direct Tuning Voltage Output (30 V) Four Integrated PNP Band Buffers for 40 mA (VCC1 to 14.4 V) Output Options for the Reference Frequency and the Programmable Divider Bus Protocol for 18 or 19 Bit Transmission Extra Protocol for 34 Bit for Test and Further Features High Sensitivity Preamplifier Circuit to Detect Phase Lock Fully ESD Protected DA 1...
