PLL Tuning Circuit with I2C Bus
The MC44818 is a tuning circuit for TV and VCR tuner applications. It contains, on one chip, all the functions required for PLL control of a VCO. This integrated circuit also contains a high frequency prescaler and thus can handle frequencies up to 1.3 GHz. The MC44818 is a pin compatible drop in replacement for the MC44817, where the only difference is the MC44818 has a fixed divide–by–8 prescaler (cannot be bypassed) and the MC44817 uses the three wire bus.
The MC44818 has a programmable 512/1024 reference divider and is 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 (I2C Bus). Data and Clock Inputs are 3–Wire 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.
• 3–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
• High Sensitivity Preamplifier
• Circuit to Detect Phase Lock
• Fully ESD Protected
