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).
• 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
